Unable To Change Bidding Strategy To MAXIMIZE_CONVERSION_VALUE

[Pete Lavetsky (AdWords API Guru)]

This post will ask the same question that has been asked many times on this forum with no acceptable response by Google.

When we attempt to update a Campaign's Bidding Strategy to MAXIMIZE_CONVERSION_VALUE we get the following error if we do not set TargetROAS:

message: "The field mask updated a field with subfields: \'maximize_conversion_value\'., at operations[0]"

The previous error came from RequestID : _hq1ke6oIuwlQFfwiVV2VA

If we do set the TargetROAS we get the following different error:

message: "This operation is not permitted on this campaign type, at operations[0].update.maximize_conversion_value.target_roas"

The previous error came from ReuestID : d7nJyfK1yJR5mG1gxCUuog

This Campaign in particular is a normal Search campaign:

status : ENABLED

ad_serving_optimization_status : OPTIMIZE

advertising_channel_type : SEARCH

target_google_search : true

target_search_network : false

target_content_network : false

target_partner_search_network : false

experiment_type : BASE

serving_status : SERVING

What does "This operation is not permitted on this campaign type" mean?

Through the AdWords UI the user is able to change this Campaign Bidding Strategy to MAXIMIZE_CONVERSION_VALUE and a TargetRoas of 2.0 ... but through the API we are not able to do the same operation.
