how to paginate in drive.permissions.list using google-api-python-client

My Problem

I have a GDrive folder of which I want to list the users having access to it. Unfortunately the API doesn't return more than 100 users and the documented solutions to paginate don't work.

(!) Maybe this is related to testing on shared drives - currently I cannot reproduce on non-shared drive folders unfortunately.

What I Tried so far:

I tried the pagination solution as described in the google docs, e.g. I tried:

file_id = "12abcde"  # my folder ID
request = service.permissions().list(
  fileId=file_id, fields="permissions(type,emailAddress)", supportsAllDrives=True
)
while request is not None:
    activities_doc = request.execute()
    request = service.permissions().list_next(request, activities_doc)

the request in the loop is always None.

The returned body from the initial request as well doesn't match the one described in the docs.

Does somebody have experience on making this work?

to get the full list, you need to use the nextPageToken and place it under the pageToken parameter.

You can get the nextPageToken from the response body by adding it to the requested fields.

You can use the following sample code as reference:

    try:

        service = build('drive', 'v3', credentials=creds)
        file_id = "asdfasdfas"  # my folder ID
        permissions_list = []
        first_request = service.permissions().list(
                fileId=file_id, 
                pageSize=100, 
                supportsAllDrives=True, 
                fields="nextPageToken, permissions(type,emailAddress)"
            ).execute()
        
        permissions_list.append(first_request)

        next_Page_Token = first_request.get('nextPageToken')

        

        while next_Page_Token:

            request = service.permissions().list(
                pageToken = next_Page_Token,
                fileId=file_id,
                pageSize=100, 
                supportsAllDrives=True, 
                fields="nextPageToken, permissions(type,emailAddress)"
            ).execute()
            permissions_list.append(request)
            next_Page_Token = request.get('nextPageToken')

            

    except HttpError as error:
        # TODO(developer) - Handle errors from drive API.
        print(f'An error occurred: {error}')

Update:

This one is a sample using list_next() base in the documentation here:

    try:
        service = build('drive', 'v3', credentials=creds)

        permission_list = []
        token = 'test'

        fileID='folderID'

        request_made =  service.permissions().list(
            fileId=fileID,
            pageSize=100, 
            fields="nextPageToken, permissions(type,emailAddress)",
            supportsAllDrives=True
            )

        request = request_made.execute()
        permission_list.append(request)

        while token:
            nextpage = service.permissions().list_next(
                previous_request=request_made, 
                previous_response=request)
            request = nextpage.execute()
            token = request.get('nextPageToken')
            permission_list.append(request)
            request_made = nextpage


    except HttpError as error:
        # TODO(developer) - Handle errors from drive API.
        print(f'An error occurred: {error}')
