EOS_Auth_Credentials.ExternalType reason: invalid type

LogEOSSDK: Error: LogEOSAuth: Invalid parameter EOS_Auth_Credentials.ExternalType reason: invalid type

Returning to a project that had EOS working previously, now I’m getting this error. Combing through all the possible reasons but everything looks as it was before, I’ve tried several other types no luck.

I really like the concept of EOS but tracking down where things are going wrong feels a lot harder than it should be.
