I just noticed it's not reproduced in another machine. M1 mac has some issue?

System: OS: macOS 12.4 CPU: (4) x64 Intel(R) Core(TM) i3-8100B CPU @ 3.60GHz Memory: 62.87 MB / 8.00 GB Shell: 5.8.1 - /bin/zsh Binaries: Node: 16.9.1 - ~/.nvm/versions/node/v16.9.1/bin/node npm: 7.21.1 - ~/.nvm/versions/node/v16.9.1/bin/npm Browsers: Chrome: 102.0.5005.115 Firefox: 101.0.1 Safari: 15.5

This is a known issue, because

1. Firefox doesn't support import maps yet (currently behind a flag in 102+)
2. We use es-module-shims to shim import map support
3. es-module-shims tests native support first which throws the error (expected and doesn't affect usage)
4. We try to hide the error by detecting its message, but only in English
5. The error is shown when the browser throws non-English error messages.

So:

• The error doesn't affect usage
• It should automatically be gone once Firefox natively support import maps

Got it. Thanks.
