It's not empty, it's missing entirely. Because the client isn't sending User-Password.

That's pretty clear.

Because radtest sends a User-Password attribute.

There's no need to post double-spaced text to the list. That just makes it harder to read.

That should be fixed.

And there we have it. As expected, the authentication is EAP, not PAP. So there's no User-Password attribute.
The later debug shows it's doing EAP-MD5. Which definitely doesn't have a User-Password attribute.
What you want to do is impossible.
FreeRADIUS is an authentication server. The REST API you're using is a database, not an authentication server. Have the REST API provide the cleartext password to FreeRADIUS. FreeRADIUS will then do the right thing.
