Error while creating the new file from template

[mvvvmd]

When creating a new presentation document the error "Error while creating the new file from template" is presented to the user. The user has a Template folder and the document does not open but does get created. The user can manually open and edit the document after.

Attached the web console log:

nc_template_error-1631865855668.log

Nextcloud version: 22.1.0
OnlyOffice App version: 7.1.2
OnlyOffice version: 6.3.1

(we have not updated to the latest NC and OO because this breaks OO completely in different ways, we need to troubleshoot this in test first)

Similar issue with creating new OO files in Nextcloud. The web console log is the same as @mvvvmd attached. Here's a screenshot of the UI error:

Nextcloud version: 22.2.0
OnlyOffice App version: 7.1.2
OnlyOffice version: 6.4.1.45 (running docker container)

Odd behavior though, as if I try to create another new file of the same type, it seems to work.

[mvvvmd]

We have upgraded, same issue with presentation documents when I have a Templates folder right now. It seems somewhat intermittent, after a few tries the error does not appear however it does return.

Nextcloud version: 22.2.0
OnlyOffice App version: 7.1.2
OnlyOffice version: 6.4.1.45

Hello dear OnlyOffice team, we're experiencing this bug as well on 7.3.4, I'm just not sure if it's a problem of Nextcloud? OnlyOffice? The connector? How is it related to nextcloud/server#25090 and nextcloud/server#22426? Who could solve that?

Thanks for your support!
