I have been creating a web app that uses webapp2 framework and hosted with Google App Engine. So in order to run the webapp on LOCALHOST, I use the following command.
dev_appserver.py app.yaml
The python script that I am trying to run is in the same project folder as well, when the script is executed, I get the following error.
File "C:\Program Files (x86)\Google\google_appengine\google\appengine\ext\remote_api\remote_api_stub.py", line 256, in _MakeRealSyncCall
raise pickle.loads(response_pb.exception())
RuntimeError: NotImplementedError()
I have no clue, why it is showing this error. I tried looking at python documentation.
exception NotImplementedError:
This exception is derived from RuntimeError. In user defined base classes, abstract methods should raise this exception when they require derived classes to override the method, or while the class is being developed to indicate that the real implementation still needs to be added.
https://docs.python.org/3/library/exceptions.html#NotImplementedError
As being new to programming, unfortunately it makes no sense to me.
I might be getting this error because of:
1.The application is running on different server and I am trying to run a script that is on my PC. But the demo I downloaded also has some python scripts that are been executed by clicking a button on html page and those work fine.
- The script I am trying to execute, uses selenium web driver, it might be conflicting with the webapp2 framework.
I am not sure, why is that happening. Any suggestions please. Thanks!
