Looping with List.Generate for API calls; Fails when only one loop needed

[hauffa]

Happy Wednesday. I have the following code which calls a function that gets API results.  All works just fine as long as there's more than one loop needed (so > 500 records). I'd love to know what I'm doing wrong (and how I might write this better).  I've used this for several different APIs with success - this is the only one that is giving me issues. 

let
    Source = (wfReportId as text, optional aftCursor as text) => let Source =
            List.Generate(() =>
                [
                    Result = try fnGetComplianceFW(wfReportId, aftCursor) otherwise null
                    , afterCursor = Result[data][policyAssessments][pageInfo][endCursor]  
                ]
               
                , each [Result][data][policyAssessments][pageInfo][hasNextPage] <> false

                , each [
                    Result = try fnGetComplianceFW(wfReportId, [afterCursor]) otherwise null
                    , afterCursor  = Result[data][policyAssessments][pageInfo][endCursor]
                    ]

                , each [Result][data][policyAssessments][nodes]
               ),
        #"Converted to Table" = Table.FromList(Source, Splitter.SplitByNothing(), null, null, ExtraValues.Error)
    in
        #"Converted to Table"
in
    Source

Thanks in advance,

Thank you.  I ended up going with this. It seems to be working.

, each List.IsEmpty([Result][data][graphSearch][nodes]) = false

rethink and change the exit condition

each [Result][data][policyAssessments][pageInfo][hasNextPage] <> false
