SAML bad Request - The message of the response is not signed and the SP require it

[giovannamascarenhas]

Hello, I have a Django app that uses the package, we puted the wantMessagesSigned: True, we added this config in the admin interface as well, and we still receiving this error, I'm pretty sure the IDP sends a signature for us. Any change that we made is reflected in the application, is like the package not get the values from settings.
