How to run application server with local(forked) Chirpstack API?

[coderBerdin]

It is not clear or its not showing what should exactly do but it helps:

REST API endpoint generation using github.com/brocaar/chirpstack-api/go

The steps to make API modifications are: Make sure your chirpstack-application-server source uses a local copy or fork of chirpstack-api (https://github.com/golang/go/wiki/Modules#when-should-i-use-the-replace-directive) Update definitions in the chirpstack-api repository Re-generate the chirpstack-api Go code (see the README.md in the same repo) You should now be able to use the modified chirpstack-api in your project

After hours of searching(I am a newbie in go) there is a small piece of replace command as commented in the bottom of the Aplication Server’s go.mod file.
You can use your local api by uncommenting this line:

replace github.com/brocaar/chirpstack-api/go/v3 => …/chirpstack-api/go

Also I added this line to the GW and NS’s go.mod files to use the same api on these servers.
