Warning: Trying to access array offset on value of type null when trying to refresh a mailbox

escozul · 11 Dec 2023, 07:30

Hello,

I followed this guide to setup my mailbox: https://www.uvdesk.com/en/blog/setup-gmail-mailbox-uvdesk-open-source-helpdesk/ but when I try to run the php command that should refresh the mailbox and create the tickets I get the following output:

php bin/console uvdesk:refresh-mailbox support_mailbox@domain.ext

# Retrieving mailbox configuration details for support_mailbox@domain.ext:

  - Establishing connection with mailbox
  - Fetching all emails since 09 December 2023
  - Found a total of 1 emails in mailbox since 09 December 2023

  # Processing all found emails iteratively:

    API https://uvdesk.example.com/mailbox/listener

    - Processing email 1 of 1:
  An unexpected error occurred: Warning: Trying to access array offset on value of type null

It seems that it connects to the mailbox just fine, retrieves the emails just fine but has trouble creating the tickets.
Yes the specified mailbox contains just one email which is a test email. It should be imported and made into a ticket.
So the 1 of 1 part is correct.
I sent a second one, and same deal. processint email 1 of 2 and then ... error.

The emails in the mailbox are marked as "read" when I run the php command. Which means it's not a credentials issue.

I see that API https://uvdesk.example.com/mailbox/listener
What is this? Should I have enabled the API so that uvdesk can process icomming emails?
Something else?

@escozul
Hi, thank you for your question!

I edited your message just to remove the email addresses. Masked them to prevent you from the potential spam.

What version of UVdesk and PHP are you using?
Be sure to use a supported and updated PHP version: https://www.php.net/supported-versions.php

Suggested PHP 8.2 or PHP 8.3

An old PHP version can be part of the issue, if is not you can also check the following topic: How to debug errors and email fetching errors

escozul · 11 Dec 2023, 09:22

@peopleinside Thanks for the reply.

Also, I appreciate the email masking, but I was already using invalid emails and domains

my server uses php 8.1 as default but supports 8.2 and 8.3.
The site is set to 8.3
When running terminal I use 8.1 (php defaults to 8.1)
but I tried forcing to use 8.3 by modifying the php command to php8.3 bin/console uvdesk:refresh-mailbox support_mailbox@domain.ext but I got the same error.

peopleinside · 11 Dec 2023, 13:36

@escozul so the PHP version looks are ok.
Do you have setup UVdesk running the online wizard?

In the wizard all checks was green?
php mailparse extension is active in your running PHP?

You can try also to give a look at the link above I give to you.
The email that appear in UVdesk operator dashboard under settings is the correct support email?

Your email has special characters in the password? If yes maybe you need to remove special characters from the password.

escozul · 12 Dec 2023, 08:33

@peopleinside Hello,

I was forced to complete the setup using terminal when I had that issue with the vhost. Once I corrected it the uvdesk started working properly but I had skipped the wizard. However, php mailparse is installed (you have to install it even if you try to complete the installation using terminal. You actually get prompted to install maiplarse during the composer installation phase.)
The email is the correct email and the error appears AFTER the php command opens the first email. That first email is then marked as read. If there are more than one emails in the inbox, I get a 1 of 2 emails processing, the first one is marked as read but still get the error and the process quits.

I still wonder what that API https://uvdesk.example.com/mailbox/listener part of the echo is...

peopleinside · 12 Dec 2023, 08:41

@escozul

The error you are reporting seems is the same discussed here:
https://forums.uvdesk.com/topic/2132/an-unexpected-error-fetching-email

The discussion has been marked as solved but I don't see a real solution to this.
In the topic mentioned also UVdesk Staff has replied but no fix and no solution.

I'm sorry but is UVdesk team staff that should provide a reply and a solution to this.
I don't know how to help you.

I'm sad also the topic mentioned has no more updates from UVdesk staff.

peopleinside · 12 Dec 2023, 08:45

@escozul Try to see also the following topic, there seems the user has found how to resolve.

https://forums.uvdesk.com/topic/2184/mail-retrieval-error/14?_=1702370612730

The call to the API is not made on HTTPS, despite the redirection...
So in my case it's a problem with the HTTP server settings!

@peopleinside
Thank you for all these topics. Still browsing through them to figure out if there is a similar resolution. In my case the call to https is made properly so I don't think the issue is there.

Also I went over to the logs and captured all the errors and warnings that come up when I try to fetch the emails. Here are my logs:

Urls and usernames have been masked for protection.

These are only deprecation warnings. Should they cause fatal errors in php operations?

peopleinside · 12 Dec 2023, 14:04

@escozul

Regarding the logs: deprecation info is not an error, is just a message to developers that can be ignored by you.

Are you sure your domain is set correctly in the file config/packages/uvdesk.yaml?
How you set your domain?

Hello
in my .env, I see the following:

Is that correct? Should I have set the app secret somewhere? ... or it does not matter?

        templates:
            email: mail.html.twig

Tried to mask some. Sorry for that. They seem just fine though.

Edit:

I visited the address found here: API https://uvdesk.example.com/mailbox/listener
kept bugging me.

The result on screen was:
{"success":false,"message":"Request not supported."}
Have no idea what that is! what is it?
What about the API? When I go over to settings, the first selection is the API:

I haven't used that access token anywhere. What's it for? Should I put it in the .env file?

peopleinside · 12 Dec 2023, 14:56

@escozul

Could you try to replace the

site_url: 'helpdes.mydomain.com' # No /public here. It's properly set.

with

site_url: helpdes.mydomain.com

Then clean cache php bin/console c:c and try to fetch email again. Still facing the issue?

escozul · 12 Dec 2023, 15:06

@peopleinside

Thank you. Same error though.

peopleinside · 12 Dec 2023, 15:10

@escozul I have no others idea sorry.

All thread suggested where user are solved seems are not helping you, from what you said. I don't know what else suggest.

Usually from what I see the error can be caused by a wrong domain settings, from some server settings like HTTP and not HTTPS, there are also some fix suggested in other topics.

I'm currently not facing this issue on my active installation.
I'm sorry to see we was not able to resolve.

escozul · 12 Dec 2023, 15:21

@peopleinside
Thank you for your time.
I appreciate all your help.

Well.. Let's hope that in the following days, someone will come across this issue and help me resolve it.

@escozul I wish you to resolve

leooxx · 24 Mar 2024, 15:46

Hello,

To fix this error, you must install the php extension "maileparse"

Apt debian command : sudo apt install php8.1-mailparse

The full error message is in the log app :

{"message":"Uncaught Error: Call to undefined function PhpMimeMailParser\\mailparse_msg_create()","context":{"exception":{"class":"Error","message":"Call to undefined function PhpMimeMailParser\\mailparse_msg_create()","code":0,"file":"/web/www/uvdesk/vendor/php-mime-mail-parser/php-mime-mail-parser/src/Parser.php:195"}},"level":500,"level_name":"CRITICAL","channel":"php","datetime":"2024-03-24T16:40:04.785031+01:00","extra":{}}

escozul · 24 Mar 2024, 18:46

@leooxx Thank you.

Will try that on Tuesday and get back here to post if it's resolved or not.

escozul · 27 Mar 2024, 09:49

@leooxx Hello,
I can't find that entry on any of my logs. How do you know that the error is with the php-mailparse addon?

cause running PHP -m lists mailparse right there..

You mentioned a "logs app"... Can't find that.

peopleinside · 27 Mar 2024, 09:52

@escozul

usually when I was using UVdesk for check if the mail parse was present and detected by UVdesk I use to generate a new UVdesk instance and run the setup wizard.

The UVdesk setup wizard show you if you have all requirements.
I suggested, since long time to the UVdesk team to add a health page that help already present installation to be checked but since different months now UVdesk seems abandoned in the open source project.

I migrated to a different solution and left also the forum also if I still get an eye here sometimes
