Jwt parse error: token contains an invalid number of segments

ElizaBth · August 23, 2017, 2:02pm

Hello,

I have tried to solve this problem that i have but I didn’t achieved it, then I open this question.

First I have tried setting into lora-gateway-config and loraserver files variable GW_SERVER_JWT_SECRET using ‘openssl rand -base64 32’, when the loraserver is running i don’t have errors but when I watch the lora-gateway-config journal i have a error for a “jwt parse error”

sudo journalctl -u lora-gateway-config -f -n 50

JWT error with curl?

Okay... some back story. 1: I tried to use mosquitto_sub command (`mosquitto_su…b -t "application/[appName]/#" -v`) to view what's published, but I couldn't find the App number/ID. (I tried using the application name, and nothing is showing up. However, the web interface is definitely showing new packets being recognized...) 2: So I'm trying to find a list of applications with the gRPC API via curl (I copied the command from the web interface) but JWT isn't liking my authentication? (I used the base64 jwt random from my /etc/default config as the value for the Grpc-Metadata-Authorization object.) `{"error":"authentication failed: jwt parse error: token contains an invalid number of segments","code":16}` So am I missing something? Thanks!

and also I have tried using https://jwt.io/ and Welcome to PyJWT — PyJWT 2.8.0 documentation but I still have the error

Someone could give me support for this error

Did you set the --gw-client-jwt-token / GW_CLIENT_JWT_TOKEN? You should first create the gateway in LoRa App Server. From there you are able to retrieve this token.
