http request method %s not supported

Error message

http request method %s not supported

What it means

A switch default guard in sendRequest: httpParameters.getHttpRequestMethod() did not match GET/POST/PUT/DELETE, so no request can be dispatched. The offending input is the configured request method string — a typo, an unsupported verb (PATCH, HEAD), or a value written by an incompatible version; the message interpolates the method name.

Solutions

1. Use one of GET, POST, PUT, DELETE as the httpMethod
2. For other verbs, use a shell task with curl instead of the HTTP task
