I am new to python. Can you help me resolve this issue.

Hi @Kambaa,

It looks like the issue is caused by a missing credentials.json file, which is needed to connect to the Gmail API.

To fix this:

1. Follow this Google guide to set up Gmail API access and download the credentials.json file.

2. Place the credentials.json file in the root of your project directory (next to main.py).

3. Run the program again:

   python main.py

4. A browser window should open, prompting you to allow access to your Gmail account. Grant the permission.

That should resolve the issue! Let me know if you need further help.
