Proxy File Shadowing _redirects not working. 404 on Nuxt SPA Bundle

Trying to shadow this.
https://dashboard-dev-kiwify.netlify.app/checkout-builder/ => https://kiwify-checkout-builder-dev.netlify.app/

But it’s not working as expected, some weird things in Network Tab (using NuxtJS)

This is my _redirects file:

/checkout-builder/*    https://kiwify-checkout-builder-dev.netlify.app/:splat   200!

hi @justaashir -

before we dig in, did you see this brand new guide on debugging redirects?

I strongly suggest you give it a thorough read through and see if this fixes your problem:

if not, please post again, and we’ll try and troubleshoot.
