Specified type 'google_ads_failure' does not exist in Google Ads API v8

I have two issues:

I'm calling G-Ads API to bulk remove ads (code)

for error_detail in error_details:             # Retrieve an instance of the google_ads_failure class from the client             failure_message = gAdsServiceWrapper.client.get_type("google_ads_failure")             # Parse the string into a google_ads_failure message instance.             # To access class-only methods on the message we retrieve its type.             google_ads_failure = type(failure_message)             failure_object = google_ads_failure.deserialize(error_detail.value)             for error in failure_object.errors:                 # Construct and print a string that details which element in                 # the above ad_group_operations list failed (by index number)                 # as well as the error message and error code.                 print("A partial failure at index "                       f"{error.location.field_path_elements[0].index} occurred "                       f"\nError message: {error.message}\nError code: "                       f"{error.error_code}")                 index_array.append(error.location.field_path_elements[0].index)                 error_array.append({"error_message": error.message, "error_code": error.error_code}) 

1. I get a partial error
2. And the code fails to parse it (taken form the official website)

My terminal shows:

Partial failures occurred. Details will be shown below.
