Error during token authentication: `KeyError: 'service'`

[jvstme]

Steps to reproduce

This example uses the NVIDIA NGC registry, but the issue may be relevant for other registries too.

1. Get an NGC API key as described here.
2. Subscribe to the NVIDIA Developer Program by clicking "Get Container" here.
3. Create test.py.

   import os
   from dxf import DXF
   
   def auth(dxf, response):
       dxf.authenticate('$oauthtoken', os.getenv('NGC_API_KEY'), response=response)
   
   dxf = DXF('nvcr.io', 'nim/meta/llama3-8b-instruct', auth)
   print(dxf.get_manifest('latest'))
   

4. Run test.py

   $ NGC_API_KEY=<your-api-key> python test.py
   

Actual behavior

Expected behavior

Prints the image manifest.
