Hmm, guess I forgot to run tests / lint last minute? (I swear I did...)
Not exactly useful here, what's the best way to exclude this rule from this file entirely? |

stacktraces from it are munged and no longer point back to the error
source.
That resulted in the following unhelpful error if an internal module
was missing or misnamed:
```
internal/bootstrap/loaders.js:190
return mod.compile();
^
TypeError: Cannot read property 'compile' of undefined
```
This changes that to at least print the id that was attempted to be
loaded:
```
internal/bootstrap/loaders.js:189
if (!mod) throw new TypeError(`Missing internal module '${id}'`);
^
TypeError: Missing internal module 'internal/a'

(I actually think TypeError was the wrong choice, but ok, it probably doesn’t matter..) |

This only works specifically for the errors caused by incorrect internal module ids (however throwing here right after failure of lookup with the module id in the message still SGTM). #29624 should help printing stack traces for all kinds of errors thrown during bootstrap. |
