Error: Invalid Query

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

entityID=https://saml-proxy.mtholyoke.edu/simplesaml/module.php/saml/sp/metadata.php/default-sp&
returnIDParam=idpentityid

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 an organization and to do that automatically for the current web browser session
