Webapps: Error when starting backend

[Lo96]

Hello, 

I have an issue when running webapps backend. I get following error " 

Oops: an unexpected error occurred
Unknown AuthCtx identifier: <user_id_herexxxx>
Please see our options for getting help

HTTP code: 403, type: com.dataiku.dip.exceptions.DKUSecurityException

any ideas why this is happening ? how to solve it ? 

A first look at log shows that error is related to a not found user. Think this is related to user deletion which happened some time ago. 

Reading dataset failed: b"Failed to read variables, caused by: DKUSecurityException: Cannot retrieve user/admin properties, caused by: NotFoundException: User 'username' doesn't exist"

many thanks

Hi @Lo96, 

Have you tried restarting the backend? For further investigation you can open a support ticket with the instance diagnostic of the DSS instance.

Check the Webapp settings. What user is it set to run as? Has that user been deleted or its profile changed?

exactly the issue was related to user deletion and as webapps backend start was linked to that user, webapp crashed and that auth error was raised. 

Thanks for your support
