Missing User-Password attribute in radius auth packet

Hello Expert,
We’ve configured L2TP vpn in our mikrotik router with radius authentication.
We see mikrotik router does not send User-Password attributes in access request.
We see only User-Name attribute.
Thats why radius server is unable to accept the request.

I’ve attached the radius pcap file. Please check.

What I’m missing in the config?

My version is: 6.48.4

Regards.
