Google Cloud Storage Permissions Troubleshooting

I'm facing difficulties with Google Cloud billing permissions. The error message reads, "The billing account for the owning project is disabled in state closed."

This is the first project I've done with Google Cloud. I'm using a Python script that sends a file to Google Bucket and initializes the Speech-to-Text service. All settings seem to be correct, but the script is receiving the following error from Google:

"google.api_core.exceptions.Forbidden: 403 POST https://storage.googleapis.com/upload/storage/v1/b/your-bucket-name/o?uploadType=resumable: {
"error": {
"code": 403,
"message": "The billing account for the owning project is disabled in state closed",
"errors": [
{
"message": "The billing account for the owning project is disabled in state closed",
"domain": "global",
"reason": "accountDisabled",
"locationType": "header",
"location": "Authorization"
}
]
}
}
: ('Request failed with status code', 403, 'Expected one of', <HTTPStatus.OK: 200>, <HTTPStatus.CREATED: 201>)

Is there an experienced professional who can help me troubleshoot? I need assistance ASAP.

- Extensive knowledge of Google Cloud Platform, particularly billing permissions and management.
- Previous experience in resolving API permission issues.
- Ability to explain technical details in a comprehensible manner.

Thank you.
