If you're still using the old 2.4 software you'll also need to consult
the old documentation:

https://wiki.shibboleth.net/confluence/display/SHIB2/ResolverScriptAttributeDefinition#ResolverScriptAttributeDefinition-InformationAvailabletotheScript

$requestContext.getPeerEntityId() might be what you're after.

Unless we can convince you that there are easier methods to achieve
whatever it is you're ultimately (not literally) trying to, just stick
it into a SAML Attribute and pull it out in the SP the same way as
you've done for "uid".
