Parameter to MergeFrom() must be instance of same class

Hi, I suddenly started getting the following error in my pipeline today.

Describe the bug: I am running offline click conversion upload according to: https://github.com/googleads/google-ads-python/blob/bcee4d08df0ea037d695d1bbcb595d7ee8adf9cd/examples/remarketing/upload_offline_conversion.py

The line: _request.conversions.append(clickconversion)

throws an error:

_TypeError Traceback (most recent call last) File , line 3 1 request = client.get_type("UploadClickConversionsRequest") 2 request.customer_id = customer_id ----> 3 request.conversions.append(click_conversion) 4 request.partial_failure = True 5 conversion_upload_response = conversion_upload_service.upload_click_conversions( 6 request=request, 7 )

TypeError: Parameter to MergeFrom() must be instance of same class: expected google.ads.googleads.v15.services.ClickConversion got ClickConversion._

However, click_conversion is initiated according to the script.

_print(type(clickconversion)) <class 'google.ads.googleads.v15.services.types.conversion_upload_service.ClickConversion'>

_print(clickconversion) external_attribution_data { external_attribution_credit: 1.0 external_attribution_model: "last_google_ads_click" } gclid: "xxx" conversion_action: "customers/123/conversionActions/123" conversion_date_time: "2024-03-04 11:10:03+00:00" conversion_value: 1.10 currency_code: "EUR" consent { ad_user_data: GRANTED }

Additional info:

Problem started occurring only today (I have a scheduled pipeline calling API on a daily basis). Nothing with regards to runtime, code, or data has changed on my side.
Consent part is being added to the object correctly (for couple of days already, it was working fine).
Problem persists for both v15 and v16
