Hi there,  
I think this might be a topic for @curt? 🙂

I’m seeing an odd runtime error whenever I open our OpenZiti Browzer-protected NextJS app.

Console trace:

```auto
VM164:1 Failed to fetch RSC payload for https://mybrowzer.app. Falling back to browser navigation. TypeError: url.match is not a function

```

Browzer starts to load, then immediately falls back to standard navigation. That means that the prefetching of React doesn't work, as well as the SPA navigation.

Let me know if you’d like to reproduce this yourself - happy to issue an identity for you against the app so you can inspect the traffic directly.  
Except for this we are super satisfied with Browzer 😎

Thanks in advance!

Hi @dmuensterer, Yes, if you give me an Identity, it will help expedite the investigation.
