Reports fail with parse error

[idkmyusername]

Hello,
I am trying to generate a scheduled error - it always fails with parse error in zabbix web service logs:

zabbix_web_service[1247531]: 2025/03/03 15:25:38 ERROR: could not unmarshal event: parse error: expected string near offset 346 of 'cookiePart...'
zabbix_web_service[1247531]: 2025/03/03 15:25:38 ERROR: could not unmarshal event: parse error: expected string near offset 612 of 'cookiePart...'

Dashboards that I use are not very complicated - few SLA graphs or regular graph for an item:


The only report that seems to work right now is a one that is a global dashboard:



There is no other errors in logs even at maximum verbosity.
I guess I have checked all I could at this stage - tags in services are correct, reporting URL is correct, report writers are set to more than 0, permissions on files seem to be correct, tried to relogin, different browsers, private mode.
No error in GUI during test - email does not arrive ever:


Zabbix version: 7.2.4
System: Ubuntu Server 22.04
2CPU, 4GB RAM, usage is on about 50-60%
Chrome version 133 installed on server

I thought that it may be the issue with chromedp: https://github.com/chromedp/chromedp/issues/1491
But when I try to list version there is none installed

go list -m github.com/chromedp/chromedp
Command 'go' not found​

Would appreciate any clue what to do, thanks in advance
