File Details not showing up on sidebar

[Hawkins1212]

Nextcloud version _(eg, 29.0.5): 30.0.1
Operating system and version (eg, Ubuntu 24.04): Unix-Based (Unraid)
Apache or nginx version (eg, Apache 2.4.25): NGINX

The issue you are facing:
Anytime I try to load file details in nextcloud (under my admin account), the sidebar doesn’t actually populate and just has a spinning wheel. My logs don’t show any errors or issues with this and no errors are populated. I’ve tried restarting Nextcloud docker to no avail. I noticed this when I tried sharing (sharing is enabled) however, the issue is not necessarily linked to sharing as it occurs when I just click the file to view File Details.

Is this the first time you’ve seen this error? (Y/N): Y

Check your browser inspector. Specifically you need to monitor the Network and Console tabs while reproducing the behavior. They will likely have clues about what is going on.

Ok In the Console of “Inspector”, when I just have the folder open I get a couple of these:

11:38:24.528 Failed sending heartbeat, got: undefined
11:38:29.017 Failed sending heartbeat, got: undefined
11:39:00.138 Failed sending heartbeat, got: undefined

Then when I click to “View Details”, I get this:

11:39:17.242 TypeError: OC.MimeType is undefined
    getIconUrl Sidebar.vue:356
    getPreviewIfAny Sidebar.vue:328

    VueJS 4
    onClick actionText-fFcUPi2g.mjs:77
    handleClick NcActionButton.mjs:131

Does this shine a light onto anything?

Note that when I use Nextcloud on my phone, it works fine and can share appropriately.

Do you have any errors or warnings under Administration settings->Overview?

There were no errors in the logs however, I was about to fix the issue.

I used the CRTL + SHIFT + R (refresh cache) and it worked without issue afterwards. Bizarre but at least it works.
