Timestamp in Firebase Simulator not allowed (.) dot

Question

there's a JSON field called createdTime, its value is the Server's current timestamp (look like this {".sv":"timestamp"}), but the simulator doesn't allow having "." (dot) in field names. What should I do to simulate that?

Answer 1

As the comment by tstirrat says,

We have a fix coming that will allow .sv keys in the simulator.

it appears that this has been fixed as of today.

I made this answer so that this question is considered answered.
