Cursor ID not found

Working with Data Node.js Frameworks

I have written a small node program using Mongoose to iterate over collection using a cursor. It has about 1800 documents and is hosted in Atlas. After quite a bit of time, I start getting a Mongo Error: Cursor ID not found.

My research indicates that the cursor may be timing out but not sure how that is possible considering the operations are pretty quick. I have tried setting the timeout option to false but get an error from Atlas saying that noTimeout options are not available on this tier.

I want the cursor to loop back to the beginning when it is done. I am running everything from a setInterval.

Any help would be greatly appreciated!

const timer = setInterval(async () => {
        try { 
            person = cursor && (await cursor.next());
            /* If the cursor exists get the next person, else get a new cursor */
            if (person) {
                //do stuff...
            } else {
               console.log('Acquiring cursor...');
                cursor = await TwitterUser.find({}, '_id id_str name screen_name').cursor();
            }
        } catch (e) {
            console.log(`Cursor error... ${e.stack}`);
        }
    }, 500);
