2 arguments were passed to a function which expects 1

Hi there fellow users of Power Bi,

 

I am trying to obtain some data using an API.

I have managed to get the authentication token and managed to obtain some data, but only the first 100 items.

So now I am trying to loop through all the "pages" using count and an offset.


However I get the following error:
2 arguments were passed to a function which expects 1.

 

The below is my code, hopefully you can help me out 

 

let
// Get authorization token
Kilde = Web.Contents("https://api.XXXXXXXXX.dk/oauth2/token",
[Headers=[#"Content-Type"="application/x-www-form-urlencoded"],
Content=Text.ToBinary(Uri.BuildQueryString([grant_type="password", client_id="XXXXXXXXXXXXXXXXX", client_secret="XXXXXXXXXXXXXX", email="xxxxxxx@yyyyyyyyy.com", password="XXXXXXXXXXXXX"]))]),
KildeTekst = Text.FromBinary(Kilde),
KildeSegmenter = Splitter.SplitTextByDelimiter("&")(KildeTekst),
KildeKvps = List.Transform( KildeSegmenter,
(value) => {
List.First((Splitter.SplitTextByDelimiter("=")(value))),
List.Last((Splitter.SplitTextByDelimiter("=")(value)))
}
),
KildeKvpTabel = Table.FromList(KildeSegmenter, Splitter.SplitTextByDelimiter("=")),
#"Filtrerede rรฆkker" = Table.SelectColumns(Table.SelectRows(KildeKvpTabel, each [Column1] = "access_token"), {"Column2"}),
Token = Text.From(List.First(Table.SelectColumns(Table.SelectRows(KildeKvpTabel, each [Column1] = "access_token"), {"Column2"})[Column2])),


EntitiesPerPage = 100,
BaseUrl = "https://api.xxxxxxxxxxx.dk/v1/organizations/XXXX/vouchers",


GetJson = (Url) =>
let Options = [Headers =[#"Authorization"="Bearer " & Token]],
RawData = Web.Contents(Url, Options),
Json = Json.Document(RawData,1252)
in Json,


GetEntityCount = () =>
let Url = BaseUrl & "?count=10",
Options = [Headers =[#"Authorization"="Bearer " & Token]],
Json = Web.Contents(Url, Options),
#"Derp" = Json.Document(Json,1252),
Count = Record.Field(#"Derp"[meta],"count")
in Count,


GetPage = (Index) =>
let
Options = [Headers =[#"Authorization"="Bearer " & Token]],
Skip = "&offset=" & Text.From(Index * EntitiesPerPage),
Top = "?count=" & Text.From(EntitiesPerPage),
Url = BaseUrl & Top & Skip,
Json = GetJson(Url, Options),
Value = Json[#"value"]
in Value,


EntityCount = List.Max({ EntitiesPerPage, GetEntityCount() }),
PageCount = Number.RoundUp(EntityCount / EntitiesPerPage),
PageIndices = { 0 .. PageCount - 1 },
Pages = List.Transform(PageIndices, each GetPage(_)),
Entities = List.Union(Pages),
Table = Table.FromList(Entities, Splitter.SplitByNothing(), null, null, ExtraValues.Error)

in
Table

 

I am pretty sure it's:

Pages = List.Transform(PageIndices, each GetPage(_)),

Which is causing the issue.

 

If I take a look at GetPage = (Index) => 


I noticed in Postman it's returning me a data and meta tag:

Value = Json[#"value"]

with

Value = Json[data][#"value"]


But sadly without luck.


I really hope someone can help me, since I am pulling my hair out over this issue :S

 

Feel free to add me on skype: Futurelinkhev or hev@futurelink.dk if needed be ๐Ÿ™‚


Best regards

Hi,

 

Unfortunately, Power BI API is out of my expertise so, it's better to ask the question in more relevant thread as this one.

 

Kind Regards,
