Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can :heart:

Nextcloud version (eg, 29.0.5): 29.0.5
Nextcloud android app version: 3.29.2
It’s a cloud hosting by Hetzner, so PHP and so on will be updated regularly.

The issue you are facing: If I open a pdf file in the Nextcloud android app, the error message “The documentType parameter for the config object is invalid. Please correct it.” shows up. I know that this issue with OnlyOffice is well known and the solution is to deactivate pdf viewing in the OnlyOffice settings. For desktop, this works fine. But in the nextcloud app, pdf files are still opened in OnlyOffice and I cant deactivate that.

Is this the first time you’ve seen this error? (Y/N): No

Steps to replicate it:

Open a pdf file in the nextcloud android app with installed OnlyOffice-app but deactivated pdf viewing functionality.

Is this a bug from OnlyOffice or does anybody know a workaround. Thanks a lot for your help!
