Why am I getting an error when trying to use BSON with a list of dictionaries?

Can you provide a snippet of your code? That might make it easier for us to pinpoint the issue. Sometimes seeing the actual code can reveal the problem more clearly.

It sounds like you're trying to access the `keys` method on a list, which doesn't exist since `keys` is a method for dictionaries. Double-check your code where you're trying to serialize the list; make sure you're handling the dictionaries correctly. If you're using a recent version of Python, the error message should indicate which line the problem is on, so that could help you trace it easily.
