list_id error?

I have a flow that has been running fine until over the weekend it started failing with the error message below. I tried removing the list from the step and re-adding it. I have also included the parameters for reference, but I don't understand why it all of the sudden started failing? Any ideas?

[{"message":"The field 'list_id' contains invalid data: 'list_id' is currently not supported as a valid option.","error_name":"InvalidData","error_code":400,"raw_message":"The field 'list_id' contains invalid data: 'list_id' is currently not supported as a valid option.","error_args":[]}]
