I disagree with both of you. I believe the failure might be due to the instance having a backup task being executed.

I agree with Melissa, but I also think it could be because no instance type was included in the request.

I think the reason it failed is because the instance is in the running state.

Maybe the targeted RDS instance being a disaster recovery instance is causing the issue as well.

I believe the instance having a backup task being executed could also cause the operation to fail.

I agree with Tawna, that's one possible reason. Another could be no instance type included in the request parameters.
