Surprisingly, the problem was the browser. I was using Microsoft Edge and getting the error. When I tried logging in using another browser (Chrome), everything worked fine!

It also gives an error on Firefox.

r/expo on Reddit: is Expo Snack limited?
June 10, 2024 -

Hello,

I've been trying to deploy my app on Snack to allow ppl to test it with a simulator right away, but, even tho the project works flawless on my iOS on Expo Go on local machine and on a docker container, I can't seem to be able to use it on the mobile version of Snack.

First, I ran into a lot of compatible issues due to my package.json being formated different than what Snack allows(Only dependencies), but now the app is succesfully working on the web version, but it seems to be getting this error whenever I try iOS or Android that async functions aren't supported. Doesn't work even on my own phone when I try to run the Snack build on Expo Go, but works just as fine the development server ran on docker, which is the exactly same code.

Now, is async functions really unsupported just on Snack, is it a format problem or is it a issue I'll run into when deploying the app live? I tried looking on Expo docs, but I couldn't find any mentions to this. I want to deploy on Apple store first, but I'm waiting for my MBP to arrive, if they aren't allowed I might as well start rebuilding my logic, since I use them a lot, specially on api calls.

Is there a different way to showcase my app in an online iOS simulator like Snack that wouldn't run into this? This is my first project and I'm really enjoying it, but deploying this front-end on the web for users to test it has been the first wall I have not found a way to crack it.
