AWS Glue start trigger with API Gateway

Hi, I have tried to start a Glue trigger by API using an API Gateway, but I receive the following error: {"Output":{"__type":"com.amazon.coral.service#UnknownOperationException"},"Version":"1.0"} Here the configuration of API Gateway: Here the response log on API Gateway: Which can be the problem? Considering the returned error the problem seems into the action that is not recognized, if it is the problem, which is the correct action to use?

Thanks
