SAML SSO with SAP BI 4.3 and Entra

[fiodir_eissayou]

I am following document 2791348, How to Configure Front-End SAML Authentication on BI 4.3. I am at generating metadata from my site, but I get the following error. I am kind of lost what SP signing key is looking for. I am pretty sure it is looking into proper jks file since when I change the filename or password, it throws all kind of errors. Any suggestion on what this error means when I try to get to BOE/BI or /BOE/saml/metadata site I try to go?
