Describe the bug

I am deploying a GraphqlApi construct with a logConfig prop set with retention days as well. I am also calling api.logGroup.addMetricFilter in the same stack. However, I get this error Resource handler returned message: "The specified log group does not exist. It appears that the log group is not created even when the logConfig prop is provided upon deployment. This is causing newly deployed stacks to fail.

Expected Behavior

I would have expected the log group to be created when the API is created so that metric filters could be applied.

Current Behavior

I get a CloudFormation error of Resource handler returned message: "The specified log group does not exist and my stack fails to depoy.

Reproduction Steps

const api = new GraphqlApi(this, 'API', {
  name: 'api',
  schema: SchemaFile.fromAsset('schema.graphql'),
  logConfig: {
    fieldLogLevel: FieldLogLevel.ALL,
    retention: RetentionDays.ONE_WEEK,
    excludeVerboseContent: true
  },
});

api.logGroup.addMetricFilter('MetricFilter', {
  filterPattern: {
    logPatternString: '{ $.fieldName = "myQuery" && $.fieldInError IS TRUE }'
  },
  metricName: 'ErrorCount',
  metricNamespace: 'MyNamespace,
  metricValue: '1',
});

Possible Solution

It appears that the code is simply looking for a log group name but not actually generating its own log group when the API is created. See here. A fix for this would be to ensure the log group is actually created rather than trying to load it by name.

Additional Information/Context

Some additional context is that I'm using VTL templates for some of my API resolvers. Because they don't natively have their own log groups or metrics, I'm leveraging adding a metric filter to the main API log group which is where the template resolvers log their logs/errors to.
