如何使用页面部件在 Business Central 中创建嵌套 Web 服务？

Question

我已在 Business Central 中创建了此 API 页面：

page 60012 CustomerPL
{
    PageType = API;
    EntitySetName = 'customerPLs';
    EntityName = 'customerPL';
    APIPublisher = 'MyCompany';
    APIGroup = 'MyCompany';
    SourceTable = "Customer";
    InsertAllowed = false;
    ModifyAllowed = false;
    DeleteAllowed = false;

    layout
    {
        area(content)
        {
            repeater(Group)
            {
                field("Cliente"; Rec."No.")
                {
                    ApplicationArea = All;
                }
                part(partCustomerBanksPL; 60013)
                {
                    ApplicationArea = All;
                    EntitySetName = 'partCustomerBanksPLs';
                    EntityName = 'partCustomerBanksPL';
                    SubPageLink = "Customer No." = field("No.");
                }
            }
        }
    }
}

我的想法是在本指南

之后的嵌套 json 中提供包含银行、地址等的客户 Web 服务

这是列表部分：

page 60013 partCustomerBanksPL
{
    ApplicationArea = All;
    Caption = 'Bancos clientes PL';
    PageType = ListPart;
    SourceTable = "Customer Bank Account";
    
    layout
    {
        area(content)
        {
            repeater(General)
            {
                field("Code"; Rec."Code")
                {
                }
                field(Name; Rec.Name)
                {
                }
                field(IBAN; Rec.IBAN)
                {
                }
                field("SWIFT Code"; Rec."SWIFT Code")
                {
                }
            }
        }
    }
}

运行 GET 请求：

https://api.businesscentral.dynamics.com/v2.0/{{tenant_id}}/Sandbox_PL/ODataV4/Company('MyCompany')/customerPL?$expand=partCustomerBanksPL

我收到此错误：

{
    "error": {
        "code": "BadRequest",
        "message": "Could not find a property named 'partCustomerBanksPL' on type 'NAV.customerPL'.  CorrelationId:  34fca7a0-ae62-4218-90f1-09ad53e0cfc0."
    }
}

那么...如何像我尝试的那样在 Business Central 中使用页面部件创建嵌套 Web 服务？

编辑：更新代码以匹配名称和驼峰命名法

添加 APIVersion 属性

page 60012 CustomerPL
{
    ...
    APIPublisher = 'MyCompany';
    APIGroup = 'MyCompany';
    APIVersion = 'v1.0';
    ...

并使用以下 HTTP 请求：https://api.businesscentral.dynamics.com/v2.0//Sandbox_PL/api/MyCompany/MyCompany/v1.0/companies()/customerPLs?$expand=partCustomerBanksPL
