I want to deploy the APP Engine apps with Earth Engine, and I made all
contents following the steps of web
<https://developers.google.com/earth-engine/app_engine_intro#deploying-app-engine-apps-with-earth-engine>
(https://developers.google.com/earth-engine/app_engine_intro#deploying-app-engine-apps-with-earth-engine).
The 'oauth2client.client.SignedJwtAssertionCredentials' function in the
example "Export to Drive" has been removed, and I replace it by
'oauth2client.service_account.ServiceAccountCredentials.from_json_keyfile_name'.
I only want to upload my task to my project, and export it to my drive, so
I delete needless code.
The main code of my server.py as follow:
EE_CREDENTIALS = ee.ServiceAccountCredentials(
config.EE_ACCOUNT, config.EE_PRIVATE_KEY_FILE)
try:
ee.Initialize(EE_CREDENTIALS)
print('The Earth Engine package initialized
successfully!')
except ee.EEException as e:
print('The Earth Engine package failed to
initialize!')
except:
print("Unexpected error:", sys.exc_info()[0])
raise
JINJA2_ENVIRONMENT = jinja2.Environment(
loader=jinja2.FileSystemLoader(os.path.dirname(__file__)),
autoescape=True,

OAUTH_SCOPE = 'https://www.googleapis.com/auth/drive'
# The app's service account credentials (for Google Drive).

OAUTH_SCOPE)
APP_DRIVE_HELPER = drive.DriveHelper(APP_CREDENTIALS)
# The decorator to trigger the user's Drive permissions request
flow.

app = webapp2.WSGIApplication([

The other code is same as the example "Export to
Drive"(https://github.com/google/earthengine-api/tree/master/demos/export-to-drive)
I use the dev_appserver.py to run the app, it returns this error:

I google this error, someone thinks it is the problem of authentication,
and someone considers that the server_account may be wrong. But I have no
idea to solve it.
My service account had been whitelisted for Earth Engine access in May.
I hope I can get some help from you!
Thank you!
