First of all, please follow Forum guidelines and do not post code or potential answers here. I have edited your post to remove that information. Thanks,

As far as your problem goes, ‘pipeline’ is defined as you have it as a JavaScript variable. It is not suitable as a MongoDB query and the error message tells you that the parser stopped at position 4 (right after the ‘val’). You will need to re-cast this as part of a valid MongoDB query to have it work.

Notice that the problem shows three steps: define the pipeline variable, run the ‘validateLab1.js’ script, and post the result into the lab. If you follow the indicated steps, you should solve the problem. Good luck.
