I simply want an object field to have a period or dot in the name on Firebase. I see where it says invalid character but it seems strange to not be possible. Thanks everyone ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/0/e/0e7901ce99b31a6b8b79044d54ee15ad776991f1.jpeg) ---

This is from Firebase documentation **If you create your own keys, they must be UTF-8 encoded, can be a maximum of 768 bytes, and cannot contain `.` , `$` , `#` , `[` , `]` , `/` , or ASCII control characters 0-31 or 127. You cannot use ASCII control characters in the values themselves, either.** ---
