TypeError while executing format_file_contents

[uchenily]

my black version is 22.1.0

# pip list | grep black
black                  22.1.0

when call Black(), I got the following error:

error caught in async handler '/root/.vim/plugged/black-nvim/rplugin/python3/blacken.py:function:Black [[]]'
Traceback (most recent call last):
  File "/root/.vim/plugged/black-nvim/rplugin/python3/blacken.py", line 36, in black
    self.format_buff(buf_str, options, start)
  File "/root/.vim/plugged/black-nvim/rplugin/python3/blacken.py", line 59, in format_buff
    new_buffer = black.format_file_contents(
  File "src/black/__init__.py", line 974, in format_file_contents
TypeError: bool object expected; got int

The function is defined as follows:

def format_file_contents(src_contents: str, *, fast: bool, mode: Mode)

format_file_contents() need a bool type 'fast' rather than int, maybe fast=bool(opts["fast"]) will solve the problem.

            new_buffer = black.format_file_contents(
                to_format, fast=opts["fast"], mode=mode
            )
