[Bug]: Sharing a map broken (NC 32 & 34)

[langfingaz]

⚠️ 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 (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• Maps app is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

On the left navigation under "My maps", when I click on "Share" of a custom map, a view opens on the right. However, it does only display the map name on top and has no buttons to actually share the map.

Steps to reproduce

See video:

2026-08-18_14-52-10.mp4

Expected behavior

As explained by the user guide (https://github.com/nextcloud/maps/#sharing-map), there should be buttons for "Activity", "Comments" and "Sharing" on the view that opens to the right. When clicking on "Sharing", there should be the possibility to share with Nextcloud users or by link.

Installation method

I tested this with two new local Nextcloud 34 instances:

• Official Docker image (https://github.com/nextcloud/docker/blob/master/.examples/docker-compose/insecure/postgres/apache/compose.yaml)
• NixOS Nextcloud module with self-signed certificates

Operating system

NixOS

PHP engine version

None

Web server

Apache (supported)

Database engine version

PostgreSQL

Is this bug present after an update or on a fresh install of the server?

Is this bug present after an update or on a fresh install of the app?

Nextcloud 32

I tested two fresh installs of Nextcloud 32 as well. Again, with the container nextcloud:32-apache via HTTP and as NixOS module via self signed HTTPS certificates.

With Nextcloud 32, the share window on the right contains slightly more information. Besides the custom map name, "Activity", "Sharing" and "Versions" is visible. But the "Sharing" tab is still completely empty:
