shibboleth Idp attributes with vendor SP using Samly

I did not update idp v3 to v4
I created a completly new VM aside the v3
that new VM is centos 8 , java 11, tomcat 9 , it has it's own new EntityID and hence new cert and new metadata.
I did provide the new v4 metadata to the SP through there web import interface . I can confirm the did consumed them because when connecting to there SP I am redirected to my IDPv4 SSO URL as specified in those new metadata.
there's one point where I am unsure ... it's because the SP did not support multiple certificate when importing IDP metadata, I can only have one for signing (no encrypt) , so I did tweak a little the installed metadata/idp-metadata.xml to cope with that
I kept the
but removed the encryption one :
In conf/idp.properties I also commented out encyption.key/cert :
and in conf/credentials.xml I replace in <util:list id="shibboleth.DefaultEncryptionCredentials">
idp.encryption.key/cert with idp.signing.key/cert so that I repects SP need to have only one and unique signing cert :
# diff conf/credentials.xml conf/credentials.xml.dist
< <!-- Jehan for recruitee, just one sign cert -->
perhaps I did something wrong in all this .
Let me know if these actions could be wrong ?
I did the same with the idp V3 instance, and it worked, the VM is still there, I can roll back to v3, but it would be better to validate and run in V4 ! .

OK, Github's code search simply sucks. But the issue (and code
reference) below explains the meaning and also confirms my guess that
you've probably misunderstood/botched your IDP upgrade by using
completly new/different keys from the installer. Copying over your old
IDPv3 keys should fix that. Or redoing your IDPv4 instance, really,
because who knows how many other things you've forgotten to carry over?
"If you search for cert_not_accepted in esaml, you will find that
this error occurs when the cert fingerprint is not trusted. It is
possible for this to happen when the certificate in the idp metadata
file specified in the config does not match the one coming through
the SAML response."
