Posthog Nuxt sourcemaps failed to process

[frasza]

Bug description

I have followed the instructions to integrated @posthog/nuxt module to generate sourcemaps and track the errors, but whenever I try to run npm run generate (I am running SPA mode) I get errors in my console.

How to reproduce

1. npm install @posthog/nuxt on my existing Nuxt project
2. Added @posthog/nuxt as a module to nuxt.config.ts
3. Configurated config related to official docs and steps

What Nuxt module is doing under the hood is calling our posthog-cli.

You are getting ENOENT error which indicates that the file does not exist or can't be accessed.

Could you verify whether you are able to run this file manually?

Try running this in your terminal

C:\Users\zanfr\Development\Projects\x\web\node_modules\@posthog\cli\node_modules\.bin_real\posthog-cli.exe
