TypeError: Cannot convert undefined or null to object

Describe the bug

After pnpm i open the vscode editor

I have reviewed the historical issues, and issue #329 appears to be similar. I have provided the minimal reproducible code for reference.

In my case, when Inspect is configured in vite.config.ts, vitest vscode fails to run and start properly. The error message in the bottom right corner states, "There was an error during Vitest startup. Check the output for more details."

However, when Inspect is commented out, vitest vscode works fine.

I have also tried adding content to the exclude directories, but it was unsuccessful.

This is expected. Vitest 2 doesn't support Vite 6, and your plugin vite-plugin-inspect requires Vite 6. Upgrade to Vitest 3 beta or wait until the official release this month.
