I had an Azure blob file connecting perfect before and then this morning I came across this error.

It had to do with the crendentials I entered to access the blob storage.

Value cannot be null. Parameter name: str error

  Hi yes. There are two blob storages I have access to one requires using an SAS key and the other was accessible via my Microsoft credentials. Apparently PowerBI didn't like the fact that I was trying to access the blob storage that required my Microsoft credentials with an SAS key.
