Hi @dangerhulk26022022 👋

Welcome to the Community! 🕶

I’m not a Mongo expert, but it sounds like [this](https://www.mongodb.com/docs/v6.0/release-notes/6.0-compatibility/#legacy-opcodes-removed) may explain why you are experiencing the problem you describe.

🤔 The solution may be to `require` a different version of the _mongodb_ library. For Custom Database Connections you can use “[Can I require? - Search which node modules you can use in webtask.io](https://auth0-extensions.github.io/canirequire/)” do determine which libraries are available; looks like there are a number of library packages available for `mongodb` (see [here](https://auth0-extensions.github.io/canirequire/#mongodb) for more details) so perhaps trying an explicit version may resolve the issue. Alternatively, you can also request a version if the one you need is not available.

Hope this helps 🙂
