`glab cluster agent` errors out when executing against a self-managed environment

Summary

glab 1.50.0 is throwing errors when configured against a self-hosted instance (17.6)

Steps to reproduce

install glab with brew on Mac OS 15.1
authenticate with a token against a self-managed instance

Example Project

This is happening against a self-managed environment

What is the current bug behavior?

glab auth, config and version both throw the following warning/error about API 401 not authorized - tho it seems the commands themselves may be successful?
Attempting to use the instructions on glab cluster bootstrap, I get a panic error (The flux step was successful)

What is the expected correct behavior?

No errors.
