Unable to call Jira Rest Api as Add-on user and use overrideScreenSecurity

Question

Hello guys,

We are developing a jira cloud app and We are facing an issue trying to update a custom field not in screen with parameter overrideScreenSecurity=true

Calling the URL  /rest/api/2/issue/'issueKey?overrideScreenSecurity=true throws the error below :

403 - only connect add-on users with admin scope permission are allowed to overwrite screen security.

Looking at this error message, we tried to call the api as the addon user (oAuth / jwt-bearer) but we are not able to connect :
The error message is : 
'Add-on \'addon-test-name\' disallowed to impersonate the user because \'no valid active user exists\'' }

However, the add-on user exists and is active.

Is that the way to connect as add-on user and to use overrideScreenSecurity?

Any help would be very much appreciated !

Behavior is weird, I have created a support ticket, waiting for their feedback.

Any other thoughts are more than welcome.

@Sebastien De Luca  if uninstalling and disabling addon and reinstalling it is not helping, I suggest you take a look at this developer community question and contact Atlassian support, it seems your site might have some problem

Yes, I did that.
The first error message says I need to connect with add-on user

As my understanding, I should use this add-on user (plugin_name) for authentication and api request, but I am not able to authenticate.

The error message is : 
'Add-on \'addon-test-name\' disallowed to impersonate the user because \'no valid active user exists\'' }

And with a cloud user who is site-admin, always the same error :
403 - only connect add-on users with admin scope permission are allowed to overwrite screen security.
