how to fully load data from limited HTTP API?

For anyone who comes across this in future, the LinkedIn link above contains a sample script to recursively access Microsoft Graph API. However cut and pasting the code will not work as there are a number of errors - which are described in the comments at the bottom. The corrected code can be found here:

// ##############   BEGIN QUERY ############################
let
       // Define a Function Called GetUserDetail that takes a single parameter Path
       // that is the MS Graph API Endpoint

GetUserDetail = (Path)=>

let
       // call out to the web endpoint and convert the result to a JSON
       // Document object which is saved in the Source variable

    Source = Json.Document(Web.Contents(Path)),

      // Assign the resultant List object to NextList variable

NextList= @Source[value],

    // recursively call GetUSerDetail function using the value of the
    // @odata.nextLink as the path
    // Since @odata.nextLink is not guaranteed to always exist in the case where
    // the result is less than 100 we need to catch this and deal with it
    // using a try otherwise basically means if you error out because no
    // @odata.nextLink exisit then just return the resulting list of values you did get

result = try @NextList & @GetUserDetail(Source[#"@odata.nextLink"]) otherwise @NextList

in

    // Return the result variable as the function return

result,
               // Use the function GetUserDetail with the initial path to the object.
              // The function will run recursively until it gets all the record and then
              // loads the full result to UserDetail Variable  
               UserDetail = GetUserDetail("https://graph.microsoft.com/beta/users?$expand=manager")
in 
UserDetail
