Paginate API POST Response

I have also tried the below snippet, however the result only gives the content from the first page. There are in total 217 responses however I only get response for the first 100.

let 
    // Create a camoflouged secret from POSTMAN and plug in here
    AuthKey = "Basic <token-here",
    EntitiesPerPage = 100,
    Url = "https://adb-xxxxxx.3.azuredatabricks.net/api/2.0/clusters/events",
    Offset1 = "{
    ""cluster_id"":""xxxxx"",
    ""event_types"": [""STARTING"",""TERMINATING"",""CREATING""],
    ""limit"":" & Text.From(EntitiesPerPage) & "}",
    GetJson = (Offset_passed) =>
        let
            offset_set =  Offset_passed,
            RawData = Web.Contents(Url,[
                                   Headers = [#"Authorization"=AuthKey ,
                                              #"Content-Type"="application/json"],
                                   Content = Text.ToBinary(offset_set), Timeout=#duration(0,2,0,0)
            ]
            ),
            Json    = Json.Document(RawData)
        in  Json,       
 
    GetEntities = () =>
        let ent_Offset = Offset1,
            Json  = GetJson(ent_Offset),
            EntityCount = Json[#"total_count"]
        in  
            EntityCount,

    FnGetOnePage =
        (cur_Offset) as record =>
        let
            Json  = GetJson(cur_Offset),
            data = try Json[#"events"] otherwise null,
            next = try Json[#"next_page"] otherwise null,
            res = [Data=data, Next=next]
        in
            res,
 
    EntityCount = GetEntities(),
    PageCount   = Number.RoundUp(EntityCount / EntitiesPerPage),
    GeneratedList = List.Generate(
        ()=>[i=0, res = FnGetOnePage(Offset1)],
        each [i]<PageCount and [res][Data]<>null,
        each [i=[i]+1, res = FnGetOnePage([res][Next])],
        each [res][Data]),
    Entities = List.Union(GeneratedList)
in
    Entities
