Description

In the previous release I could add a plugin like this:

docker exec librenms lnms plugin:add socialiteproviders/saml2

Obviously, this isn't the ideal way to add a plugin since it needs to be run every time the container is recreated, but it sort of worked.

In the current version, I get this error:

Could not open input file: require

I'm not a PHP guru, so I'm not sure what changed, but I can absolutely add any other info as needed!

Here's my validate.php:

./validate.php

Expected behaviour

I expect the plugin to install, and in this case for SAML auth to work.

Actual behaviour

The plugin does not install, and errors are output to the log.

Steps to reproduce

I believe this is all that's needed to repro:

$ docker exec librenms lnms plugin:add socialiteproviders/saml2

Could not open input file: require

Logs

This is the symptom, which is that the plugin cannot be installed:

Same for me as well. It started with release 26.4.0

I'm building a custom image for myself, where I run the plugin:add command in the Dockerfile, but I get the same error.

[WindoC]

I have same problem found in by CI/CD flow. Got same error, and the error prompt didn't help.
