Firebase is not able to store data if any of the node in the json tree path contain character "." i.e period
Example
https://.firebaseio.com/path/to/node/.json
Will store the data in above specified json tree node.
However, consider below query where I have a "." character in my url
https://.firebaseio.com/path/to/node.speical/.json
It will return
{
"error": "Invalid path: Invalid token in path"
}
Is this something because firebase server have not handled this case appropriately??
Please suggest.
Yes, there are a set of special characters that Firebase does not support in it's keys. From Firebase doc -
A child node's key cannot be longer than 768 bytes, nor deeper than 32
levels. It can include any unicode characters except for . $ # [ ] /
and ASCII control characters 0-31 and 127.
You need to escape or encode those characters if they are present in your key. A simple character substitution encoding will work too.
When you access the Firebase Database through its REST API, your URLs will end in .json. But aside from that, the . character is not allowed in Firebase Database paths. So node.special is not a valid node name.
