Description

The PostHTTP processor performs a HEAD Request to the specified REST endpoint to check if the endpoint accepts FlowFiles. This check should NOT occur if "Send As FlowFile" is set to false; this will throw a 404 exception if the endpoint does not accept HEAD requests.

Encountered while using PostHTTP processor to send a POST request to /_bulk endpoint of Elasticsearch 5.3
