Async client throws error with persistent storage

[Agente3z]

Describe the bug

When you try to change the password using a client created with acreate_client, and await it, it throws this error:

Traceback (most recent call last):

Reproduction

    return await acreate_client(
        SUPABASE_URL,
        SUPABASE_ANON_KEY,
        ClientOptions(
            auto_refresh_token=True,
            persist_session=True,
        ),

async def change_password(self, email: str, old_password: str, new_password: str) -> None:
    try:
        client = await create_anon_client()
        await client.auth.sign_in_with_password({"email": email, "password": old_password})
        await client.auth.update_user({"password": new_password, "current_password": old_password})

Hi! I'd like to investigate this issue and see if I can reproduce it. If I identify the root cause, I'll open a PR.

[Agente3z]

My bad, it was my error.
Apparently the issue was with this snippet, which seems to not work in an asynchronous environment.

ClientOptions(
    auto_refresh_token=True,
    persist_session=True,
),

Sorry for the mixup. This seems to be another bug tho, I'll leave it here and change the name of the issue, feel free to close it if I missed something/not planning to fix

This isn't a bug, the acreate_client function accepts an AsyncClientOptions, not a SyncClientOptions, if you run mypy on the provided code snippet, you'll see:

error: Argument 3 to "create_client" has incompatible type "SyncClientOptions"; expected "AsyncClientOptions | None"  [arg-type]

A lot of the documentation on how to properly use the code in this repository is available through type information, so I'd advise you to run mypy (or any other type checkers) on your codebase. If any errors occur without the type checker complaining, then feel to open a PR about.
