[🐞] The "paths[1]" argument must be of type string. Received null

Which component is affected?

Qwik Rollup / Vite plugin

Describe the bug

I created a new qwik project using npm create vite@latest, and chose the qwik typescript template.

I had to change the package.json to install vite 5 instead of 6 due to a peer dependency issue.

But then when I ran npm run build, I get the following error:

error during build:
[vite-plugin-qwik-post] The "paths[1]" argument must be of type string. Received null
TypeError [PLUGIN_ERROR]: The "paths[1]" argument must be of type string. Received null
