I have this same issue as well, using ldap backend.
It only happens when the share link is accessed on a browser that is not signed in, or with a user that does not have access to the share.
Using the nextcloud aio docker environment.

Hello.

This app has been forked an astronomical times and only few work properly.
I maintain my own fork that fix this bug and rewrite a huge part of the backend to work on NC 27.

It is not on the app store for a lot of reasons, maybe one day.
