Webapps: Error when starting backend

Lo96

Hello,

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

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

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.

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

many thanks

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

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.

hi,

the error i get when restarting the backend is what i mentioned in my 1st post.

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
