Cubby & Collabora integration

[hakunamatata]

@nebulon Nope. Maybe later when I have some spare time, I will re-install cubby and do some more testing on this. But for now I am back to using nextcloud.

[nebulon]

Thanks. Would be great to get that sorted out.

I experience the same. Though *.doc files do work, *.docx don't.

[nebulon]

I still cannot reproduce this with my .docx files @wesleynuijens do you get any error somewhere? Or if possible can you share the non working document with us? If you do not want to share it publicly, you may also send it to support@cloudron.io so we can try to reproduce and fix this.

Cubby <-> Collabora on different instances.

Any idea what this console error means?

Do you see any blocked requests or other errors in the browser network tab while trying to open a document? Assuming you see this error while opening a document.

Also anything in either app logs?

@nebulon User error confirmed after 15 minutes of testing. Note: adding another domain to Collabora requires the format [a-zA-Z0-9_\-.]*domain1.org|[a-zA-Z0-9_\-.]*domain2.org plus a restart. We should probably update the settings page with this info.

[nebulon]

The required restart is a good hint which the UI should give. We will add this.

[nebulon]

After debugging this, turns out the internal app restart was broken, hence it required a whole app restart. This is fixed with next package version.

I think I may have stumbled upon the issue on my end. I have Collabora running behind Cloudflare's proxy.

When attempting to open files with spaces in their filenames via Collabora, Cubby fails to load the document and returns a 404 Not Found in the browser console. This appears to be caused by double-encoding of the file path in the WOPI handshake.

Steps to Reproduce:

1. Upload a file with a space in the name (e.g., Audit Record 2026.xlsx) to Cubby.

2. Attempt to open the file with the Collabora integration.

3. The editor opens but remains blank.

Observed Behavior:
The browser console shows a 404 error for the file path:
api/v1/files?path=%2Fhome%2F2025-11-19%2520Work%2520Orders.xlsx
The space character (%20) has been double-encoded into %2520.

Expected Behavior:
The path should be decoded correctly by the server/proxy to locate the file on disk.

Workaround Found:
Renaming the file to remove spaces (e.g., Audit_Record_2026.xlsx) resolves the issue and the file opens successfully.

Possible Solution:
Cloudron team can fix this by changing how the app handles the WOPI access_token or by ensuring the path is decoded once more before the final request.
