Section Access results in Unknown error - Qlik Sense

[NicolaiF]

Hi All

I have an app with section-access but when I run it I get "Unknown Error".

- The data-load works perfectly fine on its own without section-access.

- The data-load doesn't work with section-access even when using only a fraction of the data (FIRST 100).

- The data-load does work with section-access if I use only a dummy table.

- The data-load works with section-access and everything in a new empty app.
But I would very much prefer to save the original app due to a lot of work put into sheets and measures.

My section access table is build up like so:

Section Access;

NoConcatenate
SA:
LOAD DISTINCT

'USER' as ACCESS,
'*' as USERID,
GROUP,
GROUP AS FILTER

FROM [lib://FILE.QVD] (qvd);

Concatenate (SA)

Load * Inline [
ACCESS,USERID,GROUP,FILTER
ADMIN,ME,*,*
];
Section Application;
