Error at the end of scenario: [ERROR] [SCTP] sctp_send_data, error message: Bad file descriptor

I ran this project today according to the new Readme.md, but an error on the ns3 side caught my attention.
Is this something like a crash, or did this happen after the scenario was completely executed?

 [DEBUG] **[E2AP ASN] Encoded succesfully, encoded size = 107
[INFO ] Send data to client_fd 7
[DEBUG] in sctp send data func

[DEBUG] data.len is 107
[DEBUG] after getting sent_len

[ERROR] [SCTP] sctp_send_data, error message: Bad file descriptor
Command ['/home/ubuntu/FlexRIC/ns-O-RAN-flexric/ns-3-mmwave-oran/build/scratch/scenario-zero'] exited with code 1

you can see on the xApp side that [KPM RC]: Test xApp run SUCCESSFULLY

I've also attached a screenshot.

Thanks,
Ali
