An earlier commit added the ability to detect common API formats and extract a useful error message from the error response payload. To achieve this, if a
titleanddetailproperty are found in the error response, the response is considered to be in a known format (RFC 7807) and these values are concatenated to form a helpful error message.However, when either
titleordetailproperty are present, but the document is not intended to follow the RFC semantics, if the properties are not scalar (e.g. if the detail property is an array of field validation violations) then the concatenation of the strings causes a notice to be raised.This pull request checks that the
titleanddetailproperties are scalar before attempting to concatenate them. If they are not, no enhanced error message is provided.
