(Pyrebase) error : orderBy must be a valid JSON encoded path

Question

I use firebase and my JSON(Firebase) is as below. I want to retrieve the key values(288xxx) by using busStopName values.

My code is as below. I'll make an example with '윤정사앞'

# Retriving id by using value
def getIdByName(db, name) :
    bus = db.child("busStops").order_by_child("busStopName").equal_to(name).get()
    print(bus.key())
...

...
getIdByName(db, "윤정사앞")

My ideal result of this code was 288000001. But there are errors, which are 'Bad Request' and 'orderBy must be a valid JSON encoded path'.

Please help me...

You have to go into rules in firebase, and update rules that you can do it. In rules, in firebase, you need to update this:

{
  "rules": {
    ".read": ...
    ".write": ...
      "busStops": {
         ".indexOn": "busStopName"
     }
  }
}
