BUG getJSON when is string

[baudelioandalon]

Describe the bug when I have Test |node1 |__name:"Baudelio" |____money: 50

and I get the json this FirebaseData is blank is not null, is BLANK, and when I try get the reason error too is blank

To Reproduce Steps to reproduce the behavior:

1. Create a node with 2 elements, one with type string and the other type int
2. Use the example jsonObject with path Test/node1
3. And is blank

Expected behavior I consider that is just a error when I get different types of a json and when I received string in a json

Screenshots

IDE and its version:

• Arduino
• Version 1.8.10

ESP32 Arduino Core SDK version

• Version LAST 19 December

Additional context and when I try get the database complete don't works when I try with the path "/"

Please,I would appreciate it if you could solve it this is my email baudelio_andalon@hotmail.com if you want to talk I will available

Sorry I don't understand. Please share your test code and describe your code and what's your expectation.

Just I can't get a simple string and I think is an library problem, sorry if I'm wrong, if it only had an int value if it would work, but that's not the case, because only if I add a string it doesn't return anything

[mobizt]

This issue was fixed already in the latest update.

Please update the library.
