Initial repo push failed "[remote rejected] master -> master (hook declined)"

I cloned the repo https://github.com/jpmeijers/ttn-resin-gateway-rpi.git onto my local machine and then attempted to push it up to my balena repo. It errored-out.

Here’s part of output:

git push balena

There is more output, unfortunately since I am a “new user” I can’t put in all of the output as apparently I can only put in 5 links as a “new user.” The posting mechanism is interpreting the output as links.

It seemed pretty straightforward…I don’t know how to fix this.
