[REQUIRED] Step 3: Describe the problem
I am writing a python script that listen to the changes in firebase realtime database. The DatabaseReference.listen was working fine with firebase-admin-3.2.1 but when i updated the version of firebase-admin-3.2.1 to firebase-admin-4.0.0, the DatabaseReference.listen stopped working. It raises following exception:
Traceback (most recent call last):
File "/Users/apple/PycharmProjects/LatestSoundTranslation/main.py", line 105, in <module>
ref.listen(on_value_change)
File "/Users/apple/PycharmProjects/LatestSoundTranslation/venv/lib/python3.7/site-packages/firebase_admin/db.py", line 376, in listen
session = _sseclient.KeepAuthSession(self._client.credential)
AttributeError: '_Client' object has no attribute 'credential'
Steps to reproduce:
Install latest firebase-admin package using pip install firebase-admin==4.0.0
cred = credentials.Certificate('./google-services.json')
default_app = firebase_admin.initialize_app(cred, {
'databaseURL': 'https://your-project-id.firebaseio.com/'
})
ref = db.reference().child("any_node")
ref.listen(on_value_change)
Relevant Code:
def on_value_change(response):
print(response)
cred = credentials.Certificate('./project39172648d8c7.json')
default_app = firebase_admin.initialize_app(cred, {
'databaseURL': 'https://speechtranslate-40b4d.firebaseio.com/'
})
ref = db.reference().child("any_node')
ref.listen(on_value_change)
