@Crazybun0422 - Looks like something is trying to create a directory in `/layers/heroku_nodejs-npm-install` at runtime. I'm not surprised that you would see `EACCES` for that. Do you have any insights...

@Crazybun0422 `heroku/builder-classic:22` is deprecated, and part of the reason is that it uses an older Buildpack API (0.4, 0.10 is current). I don't think you'll be able to fix those...

Looks like the cache layer does get written correctly during the build phase, but is not available at runtime, (by design - it reduces image size to leave it out)....

Sorry, we don't have a way to modify the download urls at present, other than forking the buildpack and modifying inventory.toml. What kind of restrictions do you have? It sounds...

When `node_modules` gets fairly large, it's possible that `rm -rf "$build_dir/node_modules/*"` gets expanded to a massive command and hits `Argument list too long` errors. So, I'm not a fan of...

> $ cat /sys/fs/cgroup/memory/memory.limit_in_bytes 9223372036854771712 That seems like a bit more than 512MB! For what it's worth, I think `dokku` setups return a similarly large value. I would be interested...

This area is also problematic for https://github.com/heroku/languages-github-actions, which depends on `libcnb-data` for `buildpack.toml` parsing. It forces `languages-github-actions` to use `libcnb-data` `0.17.0` (so that buildpacks with `[[stacks]]` are supported), or `libcnb-data`...

I dug into the cached docker volume. It looks like the values are stored as integers there: ``` $ docker run -it --rm -v=pack-cache-library_sample_latest-411aa02e5253.build:/tmp/build --entrypoint bash sample heroku@85a7fa18b759:/workspace$ cat /tmp/build/committed/io.buildpacks.lifecycle.cache.metadata...

I really like the chained form and would hate to lose it, but I also had this issue recently. For more complex modification, what about a mutation function to avoid...
