The credentials may be enough to pass `docker login`, but are they authorized to pull the image you're trying to pull with `getRegistryImage`? Try that locally, I believe it will also fail

Nope. I am authorised to pull the image locally.
I also use the credentials on a server.
I am currently using a PAT with full-access for debugging.

Can you share your code that's pulling the image?

I think I am hitting this issue :disappointed:
