Introduction

Good morning every one, I know Iterative for two years now, and I like very much your softwares. Then I have discovered PyDrive2 yesterday, as it is the best library to help me doing an upload to a shared gdrive folder, from a remote host, in a cloud function. Let me show you that.

Diagram of the program

Here is the principle of my Python program :

Sum up

As you told on your documentation, for a non-human authentication, I’ve written a settings.yaml, and downloaded a service account key, attached to my project.

But before tell you more, may I say that, the upload works well with a human authentication. My file is correctly set into the folder with its content.

In fact, my problem is that I have an error of FILE NOT FOUND, when I launch my program with GoogleAuth().ServiceAuth()

Code

def login_with_service_account():
    """
    Google Drive service with a service account.
    note: for the service account to work, you need to share the folder or
    files with the service account email.

    :return: google auth
    """
    # Define the settings dict to use a service account
    # We also can use all options available for the settings dict like
    # oauth_scope,save_credentials,etc.
    settings = {
                "client_config_backend": "service",
                "service_config": {
                    "client_json_file_path": "service-secrets.json"
                }
            }
    # Create instance of GoogleAuth
    gauth = GoogleAuth(settings=settings)
    # Authenticate
    gauth.ServiceAuth()
    return gauth

def upload_to_gdrive(filename="download.png"):
    global GDRIVE_FOLDER_ID
    mimetypes = get_mimetypes()
    fileformat = filename.split(".")[-1]

    # Create GoogleDrive instance with authenticated GoogleAuth instance.
    drive = GoogleDrive(login_with_service_account())
    metadata = {
        'parents': [
            {"id": GDRIVE_FOLDER_ID}
        ],
        'title': filename,
        'mimeType': mimetypes[fileformat]
    }
    # Create file
    file = drive.CreateFile(metadata)
    file.SetContentFile(filename)
    file.Upload()

def dofunction():
    upload_to_gdrive()
    return "Return function"

if __name__ == "__main__":
    dofunction()

Error

It sent (I've changed sensible information in the text).

Question

I really don't understand, why it is complaining about the File not found, whereas it is a folder, except if it could be a problem with the service account.

Do you have any kind of idea to help me resolve this problem, or is it something not implemented yet ?

Thanks in advance.
