Error: Invalid Query

The web server received an invalid query because there are some arguments missing
The following arguments were received:

entityID=https://emploi.cnrs.fr/sp

A valid SAML2 request needs at least the arguments entityID and return with valid values. Instead of the return argument, metadata for the Service Provider can include a DiscoveryResponse endpoint. Optionally the arguments isPassive, policy and returnIDParam can be supplied to automtically redirect the web browser to a Home Organisation and to do that automatically for the current web browser session
