337 |         }
338 |         try {

• Reproduce Code:

idnex.ts:

import { Client } from "@notionhq/client";
const notion = new Client({ auth: "secret_dummy" });
const response = await notion.databases.query({
    database_id: "dummy",
    filter: {
        property: 'Name',
        title: {
            "equals": "test"
        }
    }
});

What is the expected behavior?

Can fetch.

(This reproduce repo uses dummy api token for easy testing, so It will be "API token is invalid." error.)

What do you see instead?

Throw an runtime error.
Probably, Its related with WeakMap.

This __classPrivateFieldGet(...) returns undefined and cause this error.

Additional information

I've tested bun 0.7.1 and work fine

Version	Result
0.7.1	🟢
0.7.2	🟥
0.7.3	🟥

I think that this regression is introruded in bun 0.7.2.
