Apache beam version: 2.62.0

Code block:
from apache_beam.io.filesystems import FileSystems with FileSystems.open(gcs_file_uri, 'rb') as file: raw_content = file.read()

where gcs_file_uri is GCS path of the file

Error function: _fetch_to_internal_buffer in module: https://beam.apache.org/releases/pydoc/current/_modules/apache_beam/io/filesystem.html
Line: while not self._read_eof and (self._read_buffer.tell() -
self._read_position) < num_bytes:

where while passing nothing in file.read(), the condition is comparing 0 < None which is uncomparable and hence raising exception.
When passing file.read(10000), its comparing 0<0 which is satisfying the condition and hence working fine.
