API loop with List.Empty - access column from previous step

[MarkusEng1998]

Thanks to @lbendlin, I found a tip to terminate an API loop with List.Empty.

However my reference to the projNo column in the List.Generate() is erroring when I expand the table list.

#"02ListGenerate = Table.AddColumn(#"01filterProject", "dRofusRecord", each List.Generate(() =>
		[proj = [projNo], skip = 0,  top = 50, recordList = getURI(proj, top, skip)],

		each not List.IsEmpty([recordList]),
	
		each [proj=[projNo],
			skip = [skip] + [top], 
			top = [top],
			recordList = getURI(proj, top, skip)]
))

Thank you for any guidance.

What's the error message?

Expression.Error: The field 'projNo' of the record wasn't found.

getURI()

(projNo as text, topVal as number, skipVal as number)=>
let
    #"FilterColumnTable" = Table.SelectRows(#"102APImapRooms100", each ([ObjectType] = "rooms")),
    GetWebContents =
        Web.Contents(
            "https://api-us.drofus.com/api/company/",
            [
                RelativePath= projNo
                & "/rooms" 
                & "?$select=" & Text.Combine(#"FilterColumnTable"[dRofus.ID], ",")
                & "&$top=" & Number.ToText(topVal)
                & "&$skip=" & Number.ToText(skipVal) 
            ]
        ),
    convertedJson = Json.Document(GetWebContents,65001),     
        in
            convertedJson

In the List.Generate() I changed proj=[projNo] to projNo = [projNo].

This now works!

= Table.AddColumn(#"01filterProject", "dRofusRecord", each List.Generate(() =>
[projNo = [projNo], skip = 0,  top = 50, recordList = getURI(projNo, top, skip)],

each not List.IsEmpty([recordList]),

each [projNo = [projNo],
      skip = [skip] + [top], 
      top = [top],
       recordList = getURI(projNo, top, skip)]
))

Thank you again @lbendlin for prompting the question. I appreciate this forum because submitting the question forces me to better understand the "problem statement."
