Apollo Router : Error when starting up with

Even with the supershema example provided to test Apollo Router i’m always receiving this error from the
Router:

ERROR request{method=POST uri=/ version=HTTP/1.1}: tower_http::trace
::on_failure: response failed classification=Status code: 500 Internal Server Error

Any help will be appreciated !

Hope you got this sorted! I’ll close this, but if you’re still having problems, please look for an existing issue on Apollo Router’s GitHub and open a new issue if one doesn’t already exist.
