3242756 - Problem with SAML 2.0 authentication - given XML Saml Config is invalid

I am trying to set up SAML SSO but I get the following error message after pasting the XML metadata in the field:

The given XML Saml Config is an invalid XML document

Image/data in this KBA is from SAP internal systems, sample data, or demo systems. Any resemblance to real data is purely coincidental.

Your XML metadata file is not valid. Please use the URL of the metadata and just copy and paste it in the XML Metadata field. It is expected to be one line without any additional line breaks.
