[Bug]: Override tag causes yaml error

[dcflachs]

Version

2026.03.28

Unraid Version

7.2.4

Bug Description

Compose files allow the use of the custom yaml tags !override, !reset, !merge. This seems to break the yaml parsing in the compose manager ui. It shows up as an error in the Compose file editor as well as breaking the WebUI Labels view.

Expected Behavior

Yaml parsing should either not fail when the tags are present.

Steps to Reproduce

1. Have a compose file with the custom tags as below.
