Error when connecting to gmail using Open connectors

Hi Experts ,

I'm trying to establish connection with gmail using Open conenctors (Gmail) in CPI .

I have created the OAuth API key & OAuth API Secret key from the Google Developer console .

Have created the gmail instance in Open connector and did all the required setup .

Also configured the receiver connector (Open connector ) . Screen shot attached .

I'm using a JSON format to send the data . However when sending data I get the below error .

" com.sap.it.rt.adapter.openconnectors.exceptions.OpenConnectorsException: HTTP operation failed : status code : 405"

Can someone help me with the same please . Connector config , Error screen shot and input JSON screen shot is attached herewith .
