Storage Upload Error Typescript Issue

[mkmoisen]

Bug report

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

Describe the bug

The error returned from supabase.storage.from(...).upload has a typescript issue. It it supposed to be returning a StorageError which should have a status as a number, but it seems to be returning some other exception which instead contains a statusCode as a string.

To Reproduce

Upload a file to a location where a file already exists.

    const { data, error } = await supabase.storage.from(
        'foos'
    ).upload(
        'bar.txt', 
        someFile
    );

    if (error) {
        console.log('error is', error);
    }
    if (error && error.statusCode !== "409") {
        // 409 means we've already uploaded this photo
        throw error;
    }

Expected behavior

Logging the error shows:

error is {
  statusCode: "409",
  error: "Duplicate",
  message: "The resource already exists"
}

However, error.statusCode results in the following typescript error:

Property 'statusCode' does not exist on type 'StorageError'.

The upload is supposed to return a StorageError

StorageError however has no such statusCode, so it seems that it is not returning a StorageError.
