Content-Type not set to application/json (does not work when using a dart client)

[adamlofts]

When inserting data using the dart bigquery API the client crashes.

Unhandled exception:
ApiRequestError(message: Unable to read response with content-type text/plain; charset=utf-8.)
#0      ApiRequester.request (package:_discoveryapis_commons/src/clients.dart:86:9)
<asynchronous suspension>
#1      DatasetsResourceApi.insert (package:googleapis/bigquery/v2.dart:234:32)

The problem seems to be that although the response is JSON the Content-Type header is text/plain. You can see the dart code checking for this here:

Stream<String>? _decodeStreamAsText(http.StreamedResponse response) {
  // TODO: Correctly handle the response content-types, using correct
  // decoder.
  // Currently we assume that the api endpoint is responding with json
  // encoded in UTF8.
  if (isJson(response.headers['content-type'])) {
    return response.stream.transform(const Utf8Decoder(allowMalformed: true));
  } else {
    return null;
  }
}

Would suggest fixing by setting Content-Type: application/json; charset=utf-8 on all JSON responses.
