manager_core.InvalidChannel: https://raw.githubusercontent.com/ltdrdata/ComfyUI-Manager/main

Hello
I have just made a fresh comfyui install and just added comfyui manager. If I try to use the comfyui manager, I get this error ..
`[ERROR] [ComfyUI-Manager] An invalid channel was used: https://raw.githubusercontent.com/ltdrdata/ComfyUI-Manager/main

I have reinstalled manually and with git but always the same error
Any ideas what I am doing wrong?

Start with glob/manager_core.py, especially load_nightly and get_custom_nodes, then trace the call from glob/manager_server.py in default_cache_update. Reproduce the reported failure using the channel URL shown in the traceback. Done means the fresh installation no longer raises InvalidChannel for the intended channel configuration, with a regression test covering the behavior.
