Number of rows for each table in Power Query error

[juwis]

I've tried to create a table with the number of rows of every table in my Power BI report (with some exceptions) using Power Query: 

let
    #"Section1" = #sections[Section1],
    #"TableList" = List.Select(Record.FieldNames(#"Section1"), each not (Text.Contains(_,"Nøgletal:") or Text.Contains(_, "Aktuel rapport") or Text.Contains(_, "Tabeloversigt"))),
    #"RowCount" = List.Transform(#"TableList", each Table.RowCount(Expression.Evaluate("#""" &_& """", #shared))),
    #"Table" = Table.FromColumns({#"TableList", #"RowCount"}, {"Table Name", "Rows"}),
    #"Changed type" = Table.TransformColumnTypes(Table,{{"Table Name", type text}, {"Rows", Int64.Type}})
in 
    #"Changed type"

It works perfectly fine in the Power Query-editor and is (in this case) looking like this: 

But when I try to apply the changes, I get an error per row in the table, and the Rows-column is empty. When I try to see the error in Power Query-editor, the error table is empty:

Any idea what I'm doing wrong?
