@jan_blaha I did installation from the docker file like you suggested but the error still exists.
Will try to set up manually and write result after that.
Thanks for your kind answer.

@jan_blaha, thenk you for the reply.
I installed the server from docker image:
dockerfile jsreport/jsreport:2.5.0-full
Is it enough for jsreport running or should we use manual setup?

Hi all.
I Have the same issue.
@jan_blaha, I created simple template and it works but when I exported a template from Playground and imported into my server the same error occurs as @ajphillips reported.
The template I imported is: https://playground.jsreport.net/w/admin/cBFKE3RY
It works at the Playground so I assume the problem is not in the template but in the server settings.
Could you assist please?
