bug: segmentation fault during running bun test

[in-mai-space]

How can we reproduce the crash?

This happened after I created a global mock before running all the tests with bun run test.

import { mock, jest } from "bun:test";
import { MOCK_SIGNED_URL } from "./test-constants";

mock.module("@aws-sdk/s3-request-presigner", () => {
return {
getSignedUrl: jest.fn().mockResolvedValue(MOCK_SIGNED_URL),
};
});
