MissingSectionHeaderError: File contains no section headers

For me, I've seen this error because I mistakenly assume the API of .read_file() accepts a file path, but it only accepts a file handle.

i think im late for answer but it happened for me when i saved Config file as UTF-8 Try saving the file as ANSI.

There is no section header in the configuration file.

Essentially, the file consists of sections, each of which contains keys with values.
