When working through section 6.1 of the Recognition of hand-written digits with IBM Watson Machine Learning notebook, calling the Watson Machine Learning REST API to get the list of published models using:
GET /v3/wml_instances/{instance_id}/published_models
endpoint, there is a authorization (401) error with the following response text:
{"trace":"-1xmid60eblabs","errors":[{"code":"invalid_token_format","message":"Invalid token format. Bearer token format should be used.","target":{"type":"header","name":"Authorization"}}]}
The previous REST API call in the notebook to get the instance details using the authorization token returned from the /v3/identity/token endpoint worked ok.
Looks like an error in the notebook. Did the API authorization scheme change breaking the notebook?
