Vector Search ✖ TypeScript typecheck via tsc failed.
Hello everyone, I'm building on the Vector Search feature and I'm encountering an issue like this:

Re: the first error, you're trying to do a vector search in a mutation, but vector searches are only available in Convex actions, per this page in the docs: https://docs.convex.dev/search/vector-search
Re: the second error, the error message spells it out pretty clearly:
getMany isn't a property on the db object. It's a helper function, so you call it directly and pass the db value to it. Check the Stack post about the helper functions to see examples of correct usage: https://stack.convex.dev/functional-relationships-helpersVector Search | Convex Developer Hub

Thank you!
This is the next error that occurs, hope you can help me resolve it.

Please refer again to the Stack article I mentioned above. In that article, there's no mention of a
getMany relationship helper function. There are two functions that begin with that prefix, but they serve different purposes. Please read about each of them, then use the correct function name based on what you're trying to do.
