failed to connect to cloud storage after deploying to gcp app engine

Question

I'm developing a Flask app on App Engine VM. I want to upload file to Google Cloud Storage so i use storage_client = storage.Client() to connect to cloud storage. My app is working perfectly without error when testing in VM alone. However, after I deployed using gcloud app deploy and tested the upload function on my deployed app, it failed and returned Internet 500 error. The log showed the traceback and it is due to the line of code connecting to cloud storage: storage_client = storage.Client()

The specific error is __init__() takes 2 positional arguments but 3 were given shown in cloud storage library function. I have python 3.5 for this app and i really don't know how to resolve this. Any help would be really appreciated!

    super(Connection, self).__init__(client, client_info)

And below is my "requirements.txt":

Flask==1.0.2
gunicorn==19.9.0
firebase-admin==2.13.0
google-cloud-firestore==0.29.0
google-cloud-storage==1.17.0
lxml==3.7.3

Flask==1.0.2 gunicorn==19.9.0 firebase-admin==2.13.0 google-cloud-firestore==0.29.0 google-cloud-storage==1.17.0 lxml==3.7.3 — kdg
Is this the problem with google-cloud-storage version? thanks — kdg

You are using old libraries. Update your requirements.txt to use the current versions.

For example:

You are using google-cloud-firestore==0.29.0 but the current version is google-cloud-firestore==1.3.0

Most of your modules are out of date and in some case not compatible (and ancient library with a current library).
