使用Power Query从Power BI中的REST API获取分页数据时出现问题

Question

我目前在从REST Apo获取数据时遇到分页问题。 使用自定义查询查询REST API时，我得到的总页数是多少，但是查询是从第一页重复数据，并且不返回从其他页获取数据。

使用的自定义查询

let
BaseUrl = "--",
Token = "--",
EntitiesPerPage = 50,

GetJson = (Url) =>
let
Options = [Headers=[access_token="--", Accept="--", #"Content-Type"="--"]],
RawData = Web.Contents(BaseUrl, Options),
Json = Json.Document(RawData)
in Json,

GetEntityCount = () =>
let Url = BaseUrl & "$count=true&$top=0",
Json = GetJson(Url),
Count = Json[#"count"]
in Count,
GetPage = (Index) =>
let Skip = "$offset=" & Text.From(Index * EntitiesPerPage),
Url = BaseUrl & Skip,
Json = GetJson(Url),
Value = Json[#"items"]
in Value,

EntityCount = List.Max({ EntitiesPerPage, GetEntityCount() }),
PageCount = Number.RoundUp(EntityCount / EntitiesPerPage),
PageIndices = { 0 .. PageCount - 1 },
Pages = List.Transform(PageIndices, each GetPage(_)),
#"Converted to Table" = Table.FromList(Pages, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
#"Expanded Column1" = Table.ExpandListColumn(#"Converted to Table", "Column1"),
#"Expanded Column2" = Table.ExpandRecordColumn(#"Expanded Column1", "Column1", {"href", "id", "firstName", "lastName"}, {"Column1.href", "Column1.id", "Column1.firstName"})
in
#"Expanded Column2"

我是Power Query的新手，所以请教您有关如何解决此问题的支持和建议。
