Dynamic DataSource - Cannot find issue with code

[leemat]

Trying to get this datasource to refresh online, but am getting the dynamic datasource issue.

I've replaced the dynamic elements in the Web.Contents queries using relativepath, but am still getting the error. Any Ideas?

let
    
    // API Credentials
    oauthSite = "https://<REDACTED>.docebosaas.com",
    oauthEndpoint = "/oauth2/token",
    clientId = "<REDACTED>",
    clientSecret = "<REDACTED>",

    // User Credentials
    email = "<REDACTED>",
    pwd = "<REDACTED>",

    // Assemble Token URL
    tokenURL = "client_id=" & clientId & "&" & "client_secret=" & clientSecret & "&" & "grant_type=password&scope=api&username=" & email & "&" & "password=" & pwd,
    binaryTokenURL = Text.ToBinary(tokenURL),
    
    // Call for Token
    tokenData = Json.Document(Web.Contents("https://<REDACTED>.docebosaas.com/oauth2/token", [Headers = [#"Content-Type"="application/x-www-form-urlencoded"], Content=binaryTokenURL])),
    
    // Extract the token from the returned table
    token = tokenData[access_token],
    ver = "/analytics/v1/",
    page = "reports/",
    idReport = "2b5d6a72-0a66-43ef-9b68-70742e03e569/",
    csv = "export/csv",
    endPoint = oauthSite & ver & page & idReport & csv,
    
    
    // Retrieve Execution ID using Token
    Source = Json.Document(Web.Contents("https://<REDACTED>.docebosaas.com/analytics/v1/reports/2b5d6a72-0a66-43ef-9b68-70742e03e569/export/csv", [Headers=[Authorization="Bearer " & token, Accept="application/json"]])),
    data0 = Source[data],
    executionId = data0[executionId],
    endpoint2 = oauthSite & ver & page & idReport & "exports/" & executionId & "/results" & "?pageSize=1000",
    

    // Retrieve Paginated Data
    GetPages = (url as text, nxtToken as text) =>
    let
       GetPageData = (url as text, nxtToken as text) =>
            let 
                SourceGet = Json.Document(Web.Contents(url , [RelativePath = executionId & "/results" & "?pageSize=1000" & nxtToken, Headers=[Authorization="Bearer " & token, Accept="application/json"]])),
                dataGet = try SourceGet[data] otherwise null,
                nextTokenGet = try SourceGet[nextToken] otherwise null,    
                Encoded = try Uri.EscapeDataString(nextTokenGet) otherwise null     
               
            in
                           
                [Data = dataGet, NextToken = Encoded],
        initialData = GetPageData(url, nxtToken),
       accumulatedData = List.Generate(
           () => initialData,
            each [NextToken] <> null,
            each GetPageData(url , "&nextToken=" & [NextToken]),
            each [Data]
            
        ),
        result = List.Combine(accumulatedData)
    in
        result,
    
    GetPagesDelay = (url as text, nxtToken as text) => Function.InvokeAfter(() => GetPages(url, nxtToken), #duration(0, 0, 0, 15)),
    DataSet = GetPagesDelay("https://<REDACTED>.docebosaas.com/analytics/v1/reports/2b5d6a72-0a66-43ef-9b68-70742e03e569/exports/",""),

in
    DataSet

[RelativePath = executionId & "/results" & "?pageSize=1000" & nxtToken, Headers=[Authorization="Bearer " & token, Accept="application/json"]]))

pageSize needs to go into the Query attribute, not RelativePath.
