Hi @peopleinside ,
thank you for your reply. Here is my response to your questions:

1. The customer ticket is created by web interface
2. I am using PHP 7.3 (I have also tested it with PHP 7.4 - same issue), PHP Boost activated
3. Unfrtunately, I cannot reproduce the issue with the demo

Maybe it is related with my installation - but I have no clue why:

• I installed the latest version
• I have tested different versions of PHP (and PHP 7.3 is said to be supported by Udev according to the documentation)
• uvdesk is running on a subdomain (but I think this could not cause the issue...)

Looking forward to any ideas,
mnz42

Hi Sanjeev,
thanks for your answer!
I am using uvdesk-community-v1.0.13.

I undestand that - as obviously this is a very basic functionality, and therefore it is very likely that it works on other systems - this will be hard to reproduce on a different system, but I hope it is possible.
Here is the description on my process I apply:

• Ticket has been created by user -> it is in status "Open"

• I open the ticket, add my answer and click on "Reply" - "Submit and Close".

• The workflow then sends a E-Mail to the user and the system tells me (green rectangle in the top right) that the mail has been sent.

• Then the UI is not responding any more: it keeps on showing the moving blue balls. At the same time, symfony shows me the exception:
  UnexpectedValueException:
  The Response content must be a string or object implementing __toString(), "boolean" given.

  at vendor/symfony/http-foundation/Response.php:401
  at Symfony\Component\HttpFoundation\Response->setContent(false)
  (vendor/symfony/http-foundation/Response.php:202)
  at Symfony\Component\HttpFoundation\Response->__construct(false, 200, array('Content-Type' => 'application/json'))
  (vendor/uvdesk/core-framework/Controller/ThreadXHR.php:30)
  at Webkul\UVDesk\CoreFrameworkBundle\Controller\ThreadXHR->listTicketThreadCollectionXHR('49')
  (vendor/symfony/http-kernel/HttpKernel.php:151)
  at Symfony\Component\HttpKernel\HttpKernel->handleRaw(object(Request), 1)
  (vendor/symfony/http-kernel/HttpKernel.php:68)
  at Symfony\Component\HttpKernel\HttpKernel->handle(object(Request), 1, true)
  (vendor/symfony/http-kernel/Kernel.php:198)
  at Symfony\Component\HttpKernel\Kernel->handle(object(Request))
  (public/index.php:25)

• If I now click "back" in my browser, I see the ticket has been moved to "Closed".

• When I now click again on the ticket in the section "Closed", the system shows me the ticket (in the background), the blue moving balls in the foreground, which won't stop to move. At the same time, the same exceptions is shown in Symfony.

I hope you can give me any advice how to fix this.

Thanks and best regards!

Hello Sanjeev,
thank you for your response. What console do you mean? I have taken the Exception from Synphony. This always occurs on any ticket where I already add an answer.
Thanks,

Hello,
I am faced with the following problem: when I work on a ticket (i.e. add a reply and tag it as closed), I cannot reopen this ticket.
I always receive the following exception:

UnexpectedValueException:

Could you please help?
Thanks in advance!
