Hello @brocaar !
I’m really new to all of this, by the way thank you for your great job!
I’m trying to execute chirpstack application server from source code. What I’ve done:
make build command in app server directoryHii @Muslimah
before execute make build please run the below command to install the UI dependency.
make dev-requirements
make ui-requirements
Thank you for so quick response! 
I really appreciate your help!
I had errors while trying to execute make ui-requirements command, that I couldn’t solve using npm audit fix or npm audit fix --force. However, execution of these commands in the ui directory fixed the issue. By the way, is it okay to do so? 
But unfortunately, I still have go embed error((

I tried to run it using docker (docker-compose run --rm chirpstack-application-server bash ), the same result

I realized now this problem occured since the Refactor SQL schema migrations from sql-migrate to golang-migrate + U… commit has been done.
I did the hard reset to previous commit. It did the trick for me and now app server is successfully running on my localhost.
Hii @Muslimah
I have clone chirpstack-application-server and perform the build step and it’s working fine.
