**** update Information ***** 10-05-2023

When I try to load file with this:

let
  Source = Csv.Document(Web.Contents("https://xxx.sharepoint.com/personal/xxx/Documents/Apps/Microsoft%20Power%20Query/Uploaded%20Files/yyyy.csv"), [Delimiter = ";", Columns = 49, Encoding = 65001, QuoteStyle = QuoteStyle.None]),
  #"Promoted headers" = Table.PromoteHeaders(Source, [PromoteAllScalars = true]),
  #"Removed other columns" = Table.SelectColumns(#"Promoted headers", {"Fecha de documento"})
in
  #"Removed other columns"

it's works

but when conector is:

let
  Source = SharePoint.Files("https://xxxxx.sharepoint.com/sites/xxx/", [ApiVersion = 15]),
  #"Filtered rows" = Table.SelectRows(Source, each Text.Contains([Folder Path], "/path_file")),
  #"Sorted rows" = Table.Sort(#"Filtered rows", {{"Folder Path", Order.Ascending}}),
  #"Lowercased text" = Table.TransformColumns(#"Sorted rows", {{"Extension", each Text.Lower(_), type text}}),
  #"Filtered rows 1" = Table.SelectRows(#"Lowercased text", each ([Extension] = ".csv") and ([Folder Path] = "https://xxxxx.sharepoint.com/sites/xxxxx/Documentos compartidos/path_file/zzzzz/"))
in
  #"Filtered rows 1"
