Yaak authentication plugin stopped working on 2026.1

We have been using a custom plugin that adds a new authentication method in Yaak for many months without any issue. Now I just updated to 2026.1 and the plugin stopped working… The Auth tab from requests that used the plugin now spells UNKNOWN and when I try to send a request it errors with the message “Auth plugin not found: <auth name>” (auth name is the name defined in authentication.name in the plugin’s code).

I tried updating the package references in the plugin (now "@yaakapp/api": "^0.7.0") and rebuilding it, but to no avail.

Unfortunately the plugin is internal and I cannot share it’s full source code.
