Hey there :)
Repro:
- Open VSR
- Do something that'll change the `Field` of one of the vectors in the VSR
(promotable writer, etc)
- `vsr.syncSchema()`
- Open JsonFileWriter, `start`, `write` -> NPE
Looks like the cause is that the `fieldVectorsMap` cache isn't updated in
`syncSchema`? Possibly a few other places - `addVector`/`removeVector` too?
Cheers,
James
