After running the code I got only white blank window with above written "Google Sheets API Quickstart" about browser-samples HOT 7 CLOSED

Are you hosting the page using the Python server as shown in the quickstart instructions, or are you opening it directly from your file system? AKA, a URL of file://.

Sorry for delay reply. I am using Python server as shown in the quickstart instructions.

Did you use an existing OAuth2 client ID, or did you create a new one using the button? The error message is not something we've seen before, and I don't know what could be causing it except either not using localhost or using a client ID with a strange configuration.

I am deeply sorry being late to reply again. Last Monday I have started my new job and for this I had to be at office from morning till evening and being busy with understanding the project which I am going do in the job. That's why I couldn't manage time to sit with this issue. As the issue was around 3 weeks ago and after having the issue, I moved from that project, right now I can't remember about the environment where these issue was raised. And now I have very limited time sit with the project and fine the details.
So if you would not mind, then I will try sit with this project where I had the issue as soon as I will find some time and come back to you.
Thanks!

No worries. I'll close this issue for now, but if you find more information please add a comment and I'll reopen it.

Hello, I'm now having this issue myself. I'm using the quickstart for the Google Docs API. After following all the instructions, I get a page only showing "Google Docs API Quickstart". Python is running based on this command:

python -m http.server 8000

I get that page after loading this URL (per instructions) in browser:

http://localhost:8000 

Here is the console output I'm getting:

Serving HTTP on 0.0.0.0 port 8000 (http://0.0.0.0:8000/) ...
127.0.0.1 - - [07/Nov/2019 23:21:17] "GET / HTTP/1.1" 200 -

Any idea what is wrong?

Same thing here ... blank page with the msg Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('file://') does not match the recipient window's origin ('null') in the Console. I am unclear how to load the page on the python server and suspect that is related.... I used the file system (MacOS). Any help appreciated.
