Error dealing with pdf files

This is my code
```
def process_google_drive_documents(folder_url: str, service_account_cred: dict):
source = ab.get_source(
"source-google-drive",
config={
"folder_url": folder_url,
"credentials": {
"auth_type": "Service",
"service_account_info": json.dumps(service_account_cred),
},
"streams": [
{
"name": "pdf_loader_stream",
"globs": ["**"],
"format": {"filetype": "unstructured"},
}
],
},
)

source.check()
source.select_all_streams()
read_result = source.read()
```

And here's the error -

Any idea how to resolve this ?
