Hello,
Thank you for reaching out to us.
You have encountered the DUPLICATE_ASSET error because you are uploading an asset that has the same content with the existing asset. Please refrain from uploading duplicate asset as this is restricted in the Google Ads API.
With regard to your duplicate asset issue, a new blog post has been created for this to handle duplicate assets in Google Ads API. It states that starting the week of March 28, 2022, the Google Ads API will no longer throw an AssetError.CANNOT_MODIFY_ASSET_NAME in versions v7, v8 and v9 when uploading an asset with duplicate content but a different Asset.name. Instead, the Google Ads API will ignore the new name and return the resource name of the existing asset.
Regards,
