no office file previews

[jakobroehrl]

My office document doesn't have a preview any more:

Tested with 4.1.2 and 5beta on NC22 and NC23

Collabora is running on docker on the same server

I could reproduce this but not on the dashboard and rather just in the file list itself. It seems that removing the filesystem/dav type from app info caused that the preview providers are no longer registered when fetching the file list through webdav.

@jakobroehrl to ensure you run into the same issue, could you maybe take the file id of a docx file and try to manually access the preview with that in the browser? https://nextcloud.local/index.php/core/preview?fileId=1739472

You can get the file id as the last part when copying the "internal link" in the sharing sidebar of a file.

Might be a regression from #1728

Another finding to be filed in server, but need to check if it is an issue actually:

• Within the PreviewManager it seems that there are some places where only core preview providers get registered and not the ones from app bootstrap

Hi @juliushaertl
Yes, it's the same in the file view:

manual preview in the browser leads to: []

[juliushaertl]

Could you maybe on the nextcloud server issue the following request towards the collabora server url

curl -v https://collabora.yourserver/hosting/capabilities

This should list an entry "convert-to" that tells if the conversion api is properly configured on the Collabora server for preview generation.

{"convert-to":{"available":true},"hasMobileSupport":true,"hasProxyPrefix":false,"hasTemplateSaveAs":false,"hasTemplateSource":true,"productName":"Collabora Online Development Edition","productVersion":"6.4.14","productVersionHash":"d28ff6e"}

Not solved with Version 5 and with the latest collabora docker
In the dashboard are the previews now there, but not in the fileview

Collabora 21.11 upgraded from 6.4
Nextcloud 23.0.1RC upgraded from 22

After days debugging i can confirm that the Collabora ooxml document preview are not generated on the files app "All Files" and "Favorites" tabs and in the Folders.

But they are perfectly generated in the Dashboard, "Recent" and "Shares" tabs as well as in the "Insert an image" dialog box.

[sergeng]

is this resolved in Nextcloud 25?
