Can't read the XLSX file from http request - Damaged Excel file: Corrupted Excel file

[marcellocamara]

I can't read this xlsx file, obtained from an http request:
https://servicebus2.caixa.gov.br/portaldeloterias/api/resultados/download?modalidade=Mais-Milionaria

Example code:

final response = await get(
  Uri.parse("https://servicebus2.caixa.gov.br/portaldeloterias/api/resultados/download?modalidade=Mais-Milionaria"),
);

if (response.statusCode == 200) {
   final Excel excel = Excel.decodeBytes(response.bodyBytes);

   for (var table in excel.tables.keys) {
      print(table); // Sheet Name
   }
}

It throws the following exception when trying to print the table name:
Damaged Excel file: Corrupted Excel file.
