Automation-UpdateSSMParam document not finding payload

Question

I have used the automation-updatessm document successfully but now it keeps getting me the error below:

FunctionName
"Automation-UpdateSsmParam"
Payload
"{\"parameterName\":\"/ami/latest/us-east-1/win2k16ah-cb\", \"parameterValue\":\"ami-078c47fc7714f0cb3\"}"

OutputPayload
{"Payload":"SSM parameter not found.","StatusCode":200}
Payload
SSM parameter not found.
StatusCode
200

I have verified that the parameterName does exist. I wish there was a way to attach screenshots here.
