Getting "polling failed" after updating to camunda-external-task-client-js 3.0.1

Upgraded from v 2.1.1. to v3.0.1. Now I’m getting

:heavy_multiplication_x: polling failed with EngineError: Response code 500 (); Error: At the moment the server has to handle too many requests at the same time. Please try again later.; Type: InvalidRequestException; Code: null

I had to convert my NodeJS project from CommonJS to ESM in the process. Running v18 of NodeJS.

Turns out this was related to long polling being enabled at the same time we upgraded to 3.0.1. The warning is related to our implementation exceeding the 200 fetchAndLock max limit on active fetchAndLock requests.
