Some - not all - documents get Forbidden error on distribution from Qlikview to Qlik Sense SaaS

[simonheap]

I have connected a QlikView Server to a Qlik Sense Enterprise SaaS deployment. The Test-button under System -> Cloud Deployments works fine.

I have succes in distributing some documents to SaaS (Source Documents -> Distribute-tab on the task), but for other documents I get an error. The logfile (just) says:

20210908T100335.070+0200 Information Cloud Native (documents): Success - GetJWT for creating file
20210908T100335.071+0200 Information Starting to create file, TCS

20210908T100357.977+0200 Error Cloud Native (documents): Failure - Could not upload document to engine. statusCode= Forbidden, reason= Forbidden
20210908T100357.979+0200 Error Cloud Native (documents): Failed to import app Sales Statistics Retail.qvw to engine. Exception: Response status code does not indicate success: 403 (Forbidden).
20210908T100357.981+0200 Error Distribution to resources failed with errors. Warnings: 0, Errors: 2

Why do I get this error? What is the reason for the status code Forbidden and the 403-error?

All help is highly appreciated!

Best regards

More: the app giving me the trouble does not import manually to the SaaS either using +Add New->Upload app. I get an error "Failed to load files: 1" - and that's it.

What is preventing a Qlikview file to  be uploaded to Qlik Sense Cloud?

This case has been taken to Qlik R&D.
