Builds with Node LTS Version 12.18.3 are failing

[ohsnapitscolin]

Node's LTS Version was updated to 12.18.3 yesterday, but our Heroku builds are continuously failing on:

       Resolving node version 12 via semver.io...
       Downloading and installing node 12.18.3...
       Unable to download node 12.18.3; does it exist?
-----> Build failed

it seems like https://nodejs.org/dist/v12.18.3/node-v12.18.3-linux-x64.tar.gz exists, but I get don't just any output when running:

curl http://s3pository.heroku.com/node/v12.18.3/node-v12.18.3-linux-x64.tar.gz

Node 12.18.2 seems to be working fine:

curl http://s3pository.heroku.com/node/v12.18.2/node-v12.18.2-linux-x64.tar.gz

Hi @ohsnapitscolin, what version of the buildpack are you using? From the buildpack log, it doesn't look like you're using the latest.

Hey @danielleadams, thanks for the response! We're actually using EmberJS, and https://codon-buildpacks.s3.amazonaws.com/buildpacks/heroku/emberjs.tgz (https://github.com/heroku/heroku-buildpack-emberjs) which seems to be built on top of heroku-buildpack-nodejs.

It seems like it should be using the latest version: https://github.com/heroku/heroku-buildpack-emberjs/blob/f2f86f25c5da299f716c848a1c66880a3ef62ff6/buildpack/mrblib/buildpack/commands/compile.rb#L22

Hmmm, as quick follow up looking in more detail at our logs, it looks like we are fetching v98. Trying to figure if that's an issue on our end or with the hosted emberjs.tgz buildpack above.

After a little more investigation, I've filed heroku/heroku-buildpack-emberjs#61, and am going to close this issue on the heroku-buildpack-nodejs side. Thanks for the help!
