Generic error category class meant to be used as a data container for information deserialized from gRPC statuses (see com.daml.error.utils.DeserializedCantonError).
Generic error category class meant to be used as a data container for information deserialized from gRPC statuses (see com.daml.error.utils.DeserializedCantonError).
Note: Do NOT use this class for adding error category information to error code instances but instead re-use existing ones or define new ones (see ErrorCategory.all)
