Intermittent Issue - Cannot read properties of undefined (reading 'permission_types')

Description

Hi Team,

We keep getting this error but it resolves itself, earlier today all our users experience at the same time and there is a downtime of an hour then it got resolved again and none of us created a fix so it remains a mystery.

@markjoseultra Without more info we are not going to be able to triage this issue. aws_amplify_impl.dart and AWSAmplifyImpl are not part of our code base. If those are files in your app, please share them so we can see the code causing the issue.

Hi Team here is the code that triggers the error previously, now it works but please continue the investigation

 Future<Map<String, dynamic>> query(
    String query,
    Map<String, dynamic> variables,
  ) async {
    try {
      var operation = Amplify.API.query(
        request: GraphQLRequest<String>(
          document: query,
          variables: variables,
          apiName: "ticklr-lambda",
          headers: {
            "Authorization": await LambdaToken.generate(),
          },
        ),
      );

      var response = await operation.response.timeout(
          Duration(minutes: AppConfig.REMOTE_REQUEST_TIMELIMIT), onTimeout: () {
        throw Exception('Weak internet connection, please try again');
      });

      if (response.hasErrors) {
        throw Exception(response.errors[0].message);
      }

      if (response.data == null && response.data!.isEmpty) {
        throw Exception('Unable to fetch data from server, please try again.');
      }

      String? data = response.data;

      return jsonDecode('$data');
    } on GraphQLResponseError catch (e) {
      throw Exception(e.message.toString());
    } on ApiException catch (e) {
      throw Exception(e.message.toString());
    } on LambdaException catch (e) {
      throw Exception(e.message.toString());
    } catch (e) {
      rethrow;
    }
  }

@markjoseultra Thanks for sharing the code. Without reproducible steps or a stack trace that indicates the error is generated from Amplify Flutter we will not be able to investigate. Let us know if you can provide reproducible steps. Otherwise we will close this out. We can re-open in the future if you are able to provide more info.
