⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

After upgrading to v33, I have this issue in Safari (for macOS).
When opening a file in Nextcloud Office, the screen hangs on the activity indicator and this error is thrown in the browser web console:

[Error] InvalidCharacterError: Invalid qualified name: '@canAssign' — vue.runtime.esm.js:7399
	hl (previewUtils-mb7vuryY.chunk.mjs:2:28512)
	gl (previewUtils-mb7vuryY.chunk.mjs:2:28450)
	Ru (previewUtils-mb7vuryY.chunk.mjs:2:28126)
	(anonymous function) (previewUtils-mb7vuryY.chunk.mjs:2:29239)
	bs (previewUtils-mb7vuryY.chunk.mjs:2:28632)

Same problem when using Firefox:

DOMException: String contains an invalid character
    VueJS 25
vue.runtime.esm.js:3065:17

In Chrome, the file displays correctly in Collabora (Nextcloud Office). Therefore, this issue cannot be reproduced in Chrome.

Steps to reproduce

1. Upgrade to Nextcloud v33.0.0, upgrade all apps to latest version.
2. Open an office file.
3. The error occurs.

Expected behavior

Open the file in Collabora Online (Nextcloud Office)

Can confirm while using LibreWolf, on Chrome the issue is not present. I can't open the Markdown files.

The trace does not tell much unfortunately, maybe your server does not serve map files?

However if this happens for some people on text, the trace showing previewUtils and no hint to richdocuments and canAssign being some string I only find in server I'd expect this is rather a files isue. https://github.com/search?q=repo%3Anextcloud%2Fserver+canAssign&type=code

I'd be curious if this happens to all files or only some? Maybe related to system tags assigned to the file? Is it also an issue with images (to know if it is related to the viewer app)

In my case, images are displaying fine. I can click on the image uploaded to my Nextcloud and it opens flawlessly

It occurs with all files being opened in Nextcloud Office - Collabora (xlsx, docx, pptx) when using any browser other than Chrome. This issue does not affect images, text, or md files.

[elzody]

I think i was able to reproduce it in Firefox. It happens when there is a tag on the file.

[Vue warn]: Error in nextTick: "InvalidCharacterError: String contains an invalid character" [vue.runtime.esm.js:4625:21](http://localhost:8000/apps/viewer/node_modules/vue/dist/vue.runtime.esm.js)
DOMException: String contains an invalid character

It did not affect an image, but it also happens with an .md file I tried

If anyone has the same problem, here is how I solved it.

The issue originated from the collaborative tags assigned to documents. In my case, all my "office" documents had the tag "document" assigned. When I removed the "document" tag, I was able to open the document in CODE (Nextcloud Office) without any issues. To fix the problem once and for all, I removed the collaborative tag "document" from "Administration settings" -> "Basic settings" -> "Collaborative tags."

After deleting the "document" tag from there, all the office files became untagged and can be opened without any problems.

The trace does not tell much unfortunately, maybe your server does not serve map files?

However if this happens for some people on text, the trace showing previewUtils and no hint to richdocuments and canAssign being some string I only find in server I'd expect this is rather a files isue. https://github.com/search?q=repo%3Anextcloud%2Fserver+canAssign&type=code

I'd be curious if this happens to all files or only some? Maybe related to system tags assigned to the file? Is it also an issue with images (to know if it is related to the viewer app)

I just confirmed that it is related to the system tags assigned to the file.
