Changing Standard Bidding Strategy Type using API

[Muthu Qumar Subramanian]

Hi, 

I am trying to change the bidding strategy type of a campaign through API call. My campaign currently has a MANUAL_CPC Bidding strategy and I am trying to change it to TARGET_SPEND (Standard Bidding Strategy). I set the bidding strategy type field and target spend in Campaign Object. 
My campaign Operation looks like below: 

CampaignOperation campaignOperation =
CampaignOperation.newBuilder()
.setUpdateMask(
FieldMasks.compare(originalCampaignObject, modifiedCampaignObject)
)
.setUpdate(modifiedCampaignObject)
.build();

campaignMutateOperation =
MutateOperation.newBuilder().setCampaignOperation(campaignOperation).build();

My update Mask being set: 

 update_mask {

      paths: "bidding_strategy_type"

      paths: "end_date"

      paths: "manual_cpc"

      paths: "target_spend.cpc_bid_ceiling_micros"

    }

The mutate operation results in an error: com.google.ads.googleads.v8.errors.GoogleAdsException: errors {

  error_code {

    field_error: FIELD_CANNOT_BE_CLEARED

  }

  message: "The field cannot be cleared."

  location {

    field_path_elements {

      field_name: "mutate_operations"

      index: 0

    }

    field_path_elements {

      field_name: "campaign_operation"

    }

    field_path_elements {

      field_name: "update"

    }

    field_path_elements {

      field_name: "manual_cpc"

    }

  }

}

request_id: "_jWLPtoRuadB680s-eYsMg"

Is there anything I am missing here to update a campaign's standard bidding strategy type from Manual Cpc to Target Spend. 

Cheers,
