Phoenix little app with NO DB crashing - OOM

[factorialhr]

I created a simple Phoenix app 1.7.6 following the docs, this app is not using a DB, this just expose one simple endpoint, so no big computations of anything but when trying to deploy the beam process gets killed due to OOM, tried scaling and also adding 512MB of RAM but nothing…What am i doing wrong?

Try scaling it to 1gb and see if it starts up. I’ve had this before, and had to scale to 1 gb, not sure why.
