[Bug]: 30.0.3 share link completely broken

[LM-vb]

⚠️ This issue respects the following points: ⚠️

• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).

Bug description

After the update from 30.0.2 to 30.0.3 it is impossible to create a share link. Clicking on the arrow in the password field or the "create share" button only creates another "share link" entry. All created share link entries lack a link. This process can be repeated:

Console logs did not throw any errors.

Steps to reproduce

1. Update from 30.0.3 to 30.0.3
2. Try to create a share link
3. Fail

Additional info

I immediately reverted back to 30.0.2 (vm snapshot) after becoming aware of this bug. So I can't provide any further information.

This does not look like 30. Did you try a hard-refresh?

P.S.: I think I see what you mean though. Any other than the first link share acts up, no?

[nfebe]

That is a regression from : #49147 (No true)

Quick workaround, remove default password/date, or enforce the defaults if needed.

The icons seem to have been cached. After a shift+F5 they look like in your screenshot now (on 30.0.2).

In my test case however (30.0.3), all created links are unusable including the first one as all links were missing the URL.

[XueSheng-GIT]

Actually a duplicate of #49607 which has been ignored so far ;).

For the case it helps: I do not have the password enforcing set in administrative settings and made some tests. The problem is even more severe: Although you can create share-Links with password if not enforced in admin settings, when those share links are opened, no password necessary and link is opened!

I am on MariaDB and not on PostgreSQL btw, so not a DB provider specific issue.
