AMF not able to decode Pdu Session Resource to be switched

Dear all,

Currently we are testing HO based on Xn interface, and we stuck .
Basically after patch switch request message sent by target gNB to AMF, the AMF isn’t being able to decode the “Pdusession Resource To Be Switched Dl list IE”.
We can’t see the gtpteid and qos-flow-indentifier fields and on pcap we got.

Any hint on how to attack this issue?
