如何在新的谷歌广告python库中更新活动预算？

我正在使用谷歌广告python获取和更新活动预算

更新活动预算的以下代码失败：

def gc_cloud_set_budget(client, customer_id, budget_id, amount):
    account_budget_proposal_service = client.get_service("AccountBudgetProposalService")
    account_budget_proposal_operation = client.get_type('AccountBudgetProposalOperation')
    proposal = account_budget_proposal_operation.create
    proposal.proposal_type = client.get_type('AccountBudgetProposalTypeEnum').AccountBudgetProposalType.UPDATE
    proposal.account_budget = f"customers/{customer_id}/accountBudgets/{budget_id}"
    proposal.proposed_spending_limit_micros = int(amount * 1000000)
    field_mask = protobuf_helpers.field_mask(None, proposal._pb)
    account_budget_proposal_operation.update_mask.CopyFrom(field_mask)
    account_budget_proposal_response = (
        account_budget_proposal_service.mutate_account_budget_proposal(
            customer_id=customer_id,
            operation=account_budget_proposal_operation,
        )
    )

错误是：

google.ads.googleads.errors.GoogleAdsException: (<_InactiveRpcError of RPC that terminated with:
    status = StatusCode.INVALID_ARGUMENT
    details = "Request contains an invalid argument."
    debug_error_string = "{"created":"@1619962240.888417850","description":"Error received from peer ipv4:172.217.173.10:443","file":"src/core/lib/surface/call.cc","file_line":1062,"grpc_message":"Request contains an invalid argument.","grpc_status":3}"

    field_path_elements {

    }
  }
}

发送到google api的请求如下：

customer_id: "**********"
operation {
  create {
    proposal_type: UPDATE
    account_budget: "customers/**********/accountBudgets/**************"
    proposed_spending_limit_micros: 10000
  }
  update_mask {
    paths: "account_budget"
    paths: "proposal_type"
    paths: "proposed_spending_limit_micros"
  }
}

有什么帮助吗

customer_id: "**********"
operation {
  create {
    proposal_type: UPDATE
    account_budget: "customers/**********/accountBudgets/**************"
    proposed_spending_limit_micros: 10000
  }
  update_mask {
    paths: "account_budget"
    paths: "proposal_type"
    paths: "proposed_spending_limit_micros"
  }
}
