Gateway: could not handle packet


#1

I have a Kerlink iFemtocell gateway. The lora-gateway-bridge program is running on the gateway itself. But when a device is trying to join I get the following error.

time=“2018-10-22T08:21:11Z” level=error msg=“gateway: could not handle packet” addr=“127.0.0.1:54352” data_base64=Av29BXJ2/wA5AwSoAH19 error="invalid character ‘\x00’ looking for beginning of value"

The version of the binary is 2.6. I have tried with v2_json and protobuf marshaller. Any suggestions how to fix this?
