INVALID_TYPE
Severity : 0
Message : Expected type X but found type Y
Location: Path to where the issue occurs, params names or property names should be reported as part of the error details.
Description: Expected type X corresponds to the type inferred from data for the model/property. Specification indicates model/property is of type Y. A case like "Expected type object but found type undefined" for a response, may indicate there was no body present in the response.
How to fix the issue: Verify whether the data used as instance of the model is incorrect or the specification does not properly describe the type.

INVALID_CONTENT_TYPE
Severity : 1
Message : Invalid Content-Type (X). These are supported: Y. Example: "Invalid Content-Typ (application/octet-stream). These are supported: application/json."
Location: Applies at spec global level or operation level if explicitly specified.
Description: ARM specs use genearally content type application/json, Data plane specs may use other content types. This error surfaces quite often as the content type is not specified in the spec and the validation tool uses the default ("application/octet-stream").
How to fix the issue: this issue is not required to be fixed for ARM specs as code generation generally default to application/json. Other content-types should be explicitly specified.
