Errors

Common errors & fixes

Cannot find module 'ember-cli-esbuild-minifier'

Package is named '@nullvoxpopuli/ember-cli-esbuild' on npm, not 'ember-cli-esbuild-minifier'.

fix

Install as '@nullvoxpopuli/ember-cli-esbuild' and configure in ember-cli-build.js under 'ember-cli-esbuild' key.

The Brocfile returned undefined, which is not a valid Broccoli tree.

Misconfiguration or missing module.exports = app.toTree() in ember-cli-build.js.

fix

Ensure ember-cli-build.js ends with module.exports = app.toTree();

ESBuild error: Top-level await is not available in the configured target environment

Target set too low (e.g., 'es2015') but code uses top-level await.

fix

Set target to at least 'es2022' or a modern browser that supports top-level await.
