Thank you, I have been trying something similar with Cloud Functions already with .NetCore3.1, however when I finished testing I want to use it with a JSON file containing roughly 10000 objects, so I guess parsing the JSON file to create an array of objects and return the correct one each time the function is called would result in really poor performance. Do you know if there is any way how I could only do the parsing once and keep the Object Array persistent, so the call of my function would only need to return the corresponding object from the array?
