pulumi output

The affected integration looks like this:
```checkPingIntegration, err := apigatewayv2.NewIntegration(ctx, resName+stack+"-check-ping-integration", &amp;apigatewayv2.IntegrationArgs{
    ApiId:               gateway.ControllerApi.ID(),
    CredentialsArn:      roles.ApiGwRole.Arn,
    IntegrationType:     pulumi.String("AWS_PROXY"),
    IntegrationSubtype:  pulumi.String("StepFunctions-StartExecution"),
    PassthroughBehavior: pulumi.String("WHEN_NO_TEMPLATES"),
    RequestParameters: pulumi.StringMap{
      "StateMachineArn": checkPingStateMachine.Arn,
    },
  })
  if err != nil {
    fmt.Println(err)
  }```
As you can see, both the passthrough behaviour and the state machine ARN are defined.

As mentioned, there was no change between at all in the code between the two `pulumi up` commands ...

Is this a bug or am I doing something wrong?
