Steps to Reproduce

The automated dataloader integration added in #13664 breaks my code.

I have a dataloader like this:

export class ProductDataloader extends DataLoader {
    constructor() {
        super(async (globalIds: ReadonlyArray<string>) => {
            return batchFn(globalIds);
        });
    }

    public async loadByInternalId(id: number) {
        const globalId = toGlobalId('Product', id);
        return this.load(globalId);
    }
}

Expected Result

That code worked OK until "@sentry/node": "8.30.0"

Actual Result

After upgrade to "@sentry/node": "8.31.0" or later, calling loadByInternalId method fails:

context.dataloaders.product.loadByInternalId is not a function

Hey @michalsanger sorry for the trouble here! For now you can disable the dataloader integration like so:

Sentry.init({
  // ...
  integrations: function (integrations) {
    // filter out Dataloader integration due to bug
    return integrations.filter(function (integration) {
      return integration.name !== "Dataloader";
    });
  },
});

docs: https://docs.sentry.io/platforms/javascript/guides/node/configuration/integrations/#removing-a-default-integration

@onurtemizkan could you help investigate why this is happening?

@AbhiPrasad thanks for the workaround, works OK.
