Custom error code for missing path parameters - serverless

Question

I have a lambda function defined as

getDta:
    handler: src/handlers/data/get.getAll
    events:
      - http:
          path: groups/{groupsId}/data
          method: get
          cors: true
          private: true

If I use API like http://localhost:3000/groups//data where groupsId is missing from path please take a look again.

In this case serverless itself return 404 - Route not found. How can I override this error to 400 - Bad request?

I appreciate your suggestion! (edited)

You could create a function for path: groups/data and return 400 - Bad Request. But 404 is not a Bad Request code.

Sorry for the typo, It should be 400 - Bad request, I have edited question description

Is it really a good idea? Is there no any cleaner way? Is there nothing like configuration in serverless.yml?

And it is not like path: groups/data as you mentioned but it is like path: groups//data.
