Hey,
I am trying to send data between my phone(debugging mode via usb) and my backend server running on the computer. I managed to send GET requests without an error, but if i send a POST request the body gets lost. Why does this happen and how can i fix this?

##RequestHeader

My RequestBody reaches https pages but not http. Could that be true?

I'm not sure but this may be related to a known issue and something that restricts tauri's ipc on android as well.
https://github.com/tauri-apps/wry/pull/970
https://github.com/tauri-apps/wry/issues/1448
But i think this should really only concern requests to a custom protocol, not external servers 🤔

Thank you @olive surge again. The project where i try to implement tauri is a Nx Monorepo and it looks like the old proxy config destroies my requests. But i don't know yet. 🙂

Nope it didn't

To complete the Post. I found the bug and it was our proxy config.

Hi @faint edge , can you elaborate on your solution? I think I’m hitting the same/similar issue and would appreciate any guidance you can provide.
