Hi, I’m trying to upgrade my Neptune DB engine version, But I have this error:
Failed to modify Neptune Cluster (xxxxxx): InvalidParameterCombination: The current DB instance parameter group xxxxinstanceparametergroupxxxxx is custom. You must explicitly specify a new DB instance parameter group, either default or custom, for the engine version upgrade.
	status code: 400, request id: ba8c9fb9-a3bc-43a5-bca9-20324bca10c3
I specified the parameter group explicitly, so I don’t understand what I am missing What am I doing wrong? Thanks
