Esbuild bundling failure when using custom entry

[patwid]

Trying to start (or build) a custom entry other than the one specified in gleam.toml fails:

❌ Bundling with esbuild

I ran into an unexpected issue while trying to bundle your project with esbuild.
Here's the error message I got:

    ✘ [ERROR] Could not resolve "../dev/javascript/foo/foo.mjs"

    build/.lustre/entry.mjs:1:21:
      1 │ import { main } from "../dev/javascript/foo/foo.mjs";
        ╵                      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1 error

In the example above, there are two modules app (main) and foo (custom). Starting the main module (i.e. the one speicified in gleam.toml by running gleam run -m lustre/dev --entry=app works. Starting the custom module by running gleam run -m lustre/dev --entry=foo fails with the aforementioned error. The bundle is actually available under a different path (../dev/javascript/app/foo.mjs).

Let me know, if I can provide any further information.
