# Google Drive source connectors cannot be created by using the API

> Learn why Google Drive source connectors cannot be created using the Unstructured API due to service account key encryption requirements.

## Issue

When you try to use the [Unstructured Pipelines operations](/api-reference/workflow/overview) to
[create a source connector](/api-reference/api/source/create-source)
that connects [Google Drive](/api-reference/workflow/sources/google-drive) to Unstructured,
an error similar to the following occurs, and the source connector is not created:

```text theme={null}
API error occurred: Status 412. Body: {
    "errors": [
        {
            "field": "access_config.service_account_key",
            "message": "Field is sensitive and must be wrapped in as a secret reference or new secret value"
        }
    ]
}
```

## Cause

This error occurs because the contents of the caller's Google Drive service account's `credentials.json` file (or its
equivalent JSON string representation) must be specially encrypted and formatted before these contents are sent to Unstructured, due to the contents' size.
However, the Unstructured Pipelines operations do not support this special encryption and formatting process.

## Solution

Use the [Unstructured Pipelines](/pipelines/overview) to [create a Google Drive source connector](/pipelines/sources/google-drive) instead, as
Unstructured Pipelines does support this special encryption and formatting process.
