Error when pivoting table

Hi matheus_peppers ,
you need to create an additional column that creates a row number for the future table.
That will be calculated by adding an index column and applying a "Number.IntegerDivide"-operation on it with the number of of pivot column (rows for each batch).
Please paste the following code into the advanced editor and follow the steps:

let
    Source = Table.FromRows(
        Json.Document(
            Binary.Decompress(
                Binary.FromText(
                    "PcunFQAwCAXAXb6OSC8ybQoe+68RgsCdOSJMOASwIyxRVG1RUh1RVl1RUf1RbTQb3cawETyYHw==",
                    BinaryEncoding.Base64
                ),
                Compression.Deflate
            )
        ),
        let
            _t = ((type nullable text) meta [Serialized.Text = true])
        in
            type table [Column1 = _t, Column2 = _t]
    ),
    #"Changed Type" = Table.TransformColumnTypes(Source, {{"Column1", type text}, {"Column2", Int64.Type}}),
    #"Added Index" = Table.AddIndexColumn(#"Changed Type", "Index", 0, 1, Int64.Type),
    #"Integer-Divided Column" = Table.TransformColumns(
        #"Added Index",
        {{"Index", each Number.IntegerDivide(_, 5), Int64.Type}}
    ),
    #"Pivoted Column" = Table.Pivot(
        #"Integer-Divided Column",
        List.Distinct(#"Integer-Divided Column"[Column1]),
        "Column1",
        "Column2"
    )
in
    #"Pivoted Column"
