multi-auth-Plugin schema validation incorrect

[itbane]

Issue description

When adding a multi-auth-Plugin (tested with consumer_group), the schema validation fails with an error:

failed to check the configuration of plugin multi-auth err: property "auth_plugins" validation failed: expect array to have at least 2 items

The exact same config via curl works (copy & pasted the docs example).

Expected behavior

The multi-auth-Plugin and consumer_group are added correctly.

How to Reproduce

1. Create a new consumer_group object
2. add multi-auth plugin
3. Copy & paste the plugin config from the docs (https://apisix.apache.org/docs/apisix/plugins/multi-auth/)
4. Add the plugin

Hi, thanks for reporting this issue.

I’m investigating this on the apisix-dashboard side.
It looks like a schema validation mismatch between the Dashboard UI
and the APISIX multi-auth plugin config.

I’ll try to reproduce this locally and propose a fix in a separate PR.
