Description

Current version 0.1.3 of osmo_diameter2gsup is missing commit 7c912ff07b6fe3c91b90d0b9729bdc159da6165d which handles decoding of the APN value. If you download the tar.xz there is no src/decode_apn.erl file:

https://obs.osmocom.org/source/osmocom:latest/osmo_dia2gsup/osmo-diameter2gsup_0.1.3.tar.xz?rev=c25caecb837ba4132713daf783df7793

The logs show that the APN is not decoded (Line breaks for emphasis):
