    TODO: We really should get rid of this require statement below for a couple of reasons:
    1. It makes the integration unusable in the SvelteKit SDK, as it's not possible to use `require`
       in SvelteKit server code (at least not by default).
    2. Throwing in a constructor is bad practice

    More context for a future attempt to fix this:
    We already tried replacing it with import but didn't get it to work because of async problems.
    We still called import in the constructor but assigned to a promise which we "awaited" in
    `configureAndConnect`. However, this broke the Node integration tests as no local variables
    were reported any more. We probably missed a place where we need to await the promise, too.
