Warning: Calling `sha256 "digest" with Brew on macOS

Since the last time that I ran the brew update command in my macOS, I started to have this issue below. Running brew style --fix doesn't solve it.

How could I solve it?

macOS brew error sha256

You need to specify the path of your Formula to fix it, try to run this command below.

brew style --fix /usr/local/Homebrew/Library/Taps/henkrehorst/homebrew-bc/Formula

example

$ brew style --fix /usr/local/Homebrew/Library/Taps/pnbv/homebrew-ffmpegvidstab/ffmpeg.rb
