}What happened?
While running the tests, the browser-runner is throwing this error:
2024-11-26T16:24:44.425Z WARN @wdio/browser-runner:vite: Failed to load source map for /Users/ken/projects/dev/web/node_modules/@wdio/browser-runner/build/third_party/mocha.js.
Error: An error occurred while trying to read the map file at mocha.js.map
Error: ENOENT: no such file or directory, open '/Users/ken/projects/dev/web/node_modules/@wdio/browser-runner/build/third_party/mocha.js.map'

I can confirm there is no .map file at that location. Vite is clearly expecting it, but it's not included in the vendor bundle included with @wdio/browser-runner.
What is your expected behavior?
That Vite would run without this error.
How to reproduce the bug.
Run a unit test with a Typescript-based project, mocha and webdriverIO.
