Issue with GCP quickstart

ChirpStack Application Server
1

Hi guys,

I’m following the GCP quickstart here: https://www.chirpstack.io/project/guides/google-cloud-platform/ and have reached the point where i need to start the application server. However I keep getting the error:
FATA[0000] setup integration error: new integration error: credentials from json error: unexpected end of JSON input

I haven’t done anything outside the norm with the config file.
I’m unsure what’s causing this, has anyone had experience with this?

Cheers
Sam

I’m facing the exact issue. Were you able to resolve this?

– Fixed –

  1. Create IAM Service Key file from here: https://cloud.google.com/iam/docs/creating-managing-service-account-keys
  2. Update your configuration with the JSON file as mentioned here: https://www.chirpstack.io/application-server/install/config/ (look in [application_server.integration.gcp_pub_sub] section).

@Muhammad_Fahad_Baig I just posted the same problem, glad you got it working! Would you mind giving a bit more detail about your solution - specifically step 1 where you create a service key? Also on step 2 are you adding the entire contents of the json key? Thanks!
