Thanks for the answer Jaspreeet.

Turned out that this as me misunderstanding elasticsearch basics. I was confusing the \_source property of a doc with the mapping of an index.

If I set dynaminc to "strict" then the data sent is dropped. Having dynamic as false seems to give identical behaviour to having it as true, or undefined. Am I missing something? This is with elasticsearch v 7.10.1
