Unknown error occurred trying to invoke collector

[Guilherme Dalseno]

The issues happen with few users when trying to use the issue collector:

• [18/09/2020 11:21:44] Unknown error occurred trying to invoke collector 'Coverage Product Request' from 'x.x.x.x' by Anonymous.

I have used the instruction on - https://confluence.atlassian.com/adminjiraserver073/using-the-issue-collector-861253486.html and checked all the articles available and could not find a solution.

If I give a Jira Service Desk license to the user than it works, which may indicate that is a permission issue, as any user should be able to open a request via Issue collector without requiring an SD license. 

Thanks in advance for the help,
Guilherme

I got the similar error when I try to invoke issue collector from other application. This is what Atlassian tech suggested: https://jira.atlassian.com/browse/JRASERVER-71186?error=login_required&error_description=Login+required&state=2c7a0c7a-8391-44b1-aafe-5fce52f57dd9

And the solution is not working. What is next?
