Storage upload network error on Expo SDK 52

[Noahkoole]

Bug report

• [x] I confirm this is a bug with Supabase, not with my own application.
• [x] I confirm I have searched the Docs, GitHub Discussions, and Discord.

Describe the bug

When running a new expo app on SDK 52 on iOS simulator a file can not be uploaded that is larger then 500 KB. Otherwise it results in a network error.

When trying to upload any image file to a private mock endpoint no issue arrises so it has to do with supabase.

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

1. Install a basic expo app using the new 52 SDK. npx create-expo-app@latest --template default@beta
2. Setup the default supabase configuration
3. Try to upload a image that is larger then 500 KB-1 MB.

const { data: uploadedImage, error: uploadError } = await supabase.storage
      .from('bg_images')
      .upload(bgImageName, decode(base64), {
        contentType: 'image/' + fileExtension.slice(1),
        upsert: true,
      });

4. This throws an "Network error" which is outside of the "error" return result

This only happens in Expo Go was my discovery. Making a development build resolves all the issues. which I would recommend anyway
