I'm trying to use the oai-2023-wk14 image because I want to have access to the SRS signal which isn't enabled in the normal oai-5g-sa-ran image.  However, I can't get a working link between the UE and gNB.
I'm using scenario 10011.
To run the gNB I call "python3 ran.py -n 1 -p 106 -c 1 -t donor --numa" from within the OAI_Colosseum directory and on the UE side I call the same but "-t UE".  The UE goes through the RA procedure and seems like its going to connect, but then the gNB fails with the error

Assertion (false) failed!
In newGtpuCreateTunnel() ../../../openair3/ocp-gtpu/gtp_itf.cpp:628
SGW Address size impossible

I'm running the oai-cn5g-fed image, and have added the imsi of the ue (based on the srn id) to the oai_db.sql file.  

Thank you for your assistance.
