Hi @Glenn_B

Thanks for posting here and welcome to the community! 🥳

I’m not an expert on Mongo DB, but I believe you will have to put the keys in strings, like so:

```auto
{ "updated": { "$lt": ISODate("2021-02-25T10:03:46.000Z") } }

```

You can also have a look at a similar post from the community:

Let me know if this helps! 🙌
