insufficientFilePermissions error when try to export GDrive workspace files

Encountered insufficientFilePermissions error when try to export GDrive workspace files.

Error:

googleapiclient.http:Encountered 403 Forbidden with reason "insufficientFilePermissions"
<HttpError 403 when requesting https://www.googleapis.com/drive/v3/files/{File_ID}/export?mimeType=application%2Fvnd.oasis.opendocument.presentation&alt=media returned "
The user does not have sufficient permissions for this file.". Details: "[{
'message': 'The user does not have sufficient permissions for this file.', 
'domain': 'global', 
'reason': 'insufficientFilePermissions'
}]">

I am using python code found at Link

To test the code, I configured service_account on my GDrive account. I am able to download the Google workspace files and it is working fine. But, the same code is throwing above mentioned error for customer GDrive. I configured service_account correctly as able to download rest of the GDrive files other than worksapce.

Sharing, the GDrive workspace file structure is

>The user does not have sufficient permissions for this file.

Means exactly that the user that you are authencating with does not have permission to access the file. You are using a service account so you have two options.

One open the service account file find the service account email address. Its the only one with a @ in it go to google drive web app and share a directory with the service account like you would any other user.

The second option because you are using google workspace this is probably the best option would be to have the admin of your workspace domain to configure domain wide delegation for your service account. this will grant the service account access to impersonate any user on the workspace domain. YOu can then specify which user you want to impersonate in your code.

credentials = ServiceAccountCredentials.from_json_keyfile_name(
SERVICE_ACCOUNT_FILE_PATH,
scopes=SCOPES)
credentials = credentials.create_delegated(user_email)

Note im going to see about contacting the team about the link you posted. Seams strange how they have documented workspace drive auth to me.
