Clear error after first not working. [WSL2]

[ntaken]

Describe the bug
The copied command do not seems to work.

    # Uncomment the following line to automatically clear errors after showing
    # them once. This not only clears the error for powerline-go, but also for
    # everything else you run in that shell. Don't enable this if you're not
    # sure this is what you want.

    #set "?"

To Reproduce
Steps to reproduce the behavior:

1. Uncomment #set "?" to set "?" in .bashrc

and from different shell (like powershell) restart Ubuntu

2. wsl -terminate Ubuntu

3. Open again Ubuntu

4. Produce a error and press enter

5. The errors will keep repeting till you insert a successful command.

Expected behavior
Errors should stop repeting after showing once.

Environment (please complete the following information):

• OS: Ubuntu 20.04
• Architecture: amd64
• Shell: Bash
• WSL2

I have the same problem on native Debian Linux.

# powerline-go
function _update_ps1_powerline_go() {
    #PS1="$($GOPATH/bin/powerline-go -error $? -jobs $(jobs -p | wc -l))"
    PS1="$(powerline-go \
            -error $? \
            -jobs $(jobs -p | wc -l) \
            -numeric-exit-codes \
            -hostname-only-if-ssh \
            -shell-var PROMPT_SYMBOLS \
            -modules "time,venv,user,host,ssh,cwd,perms,jobs,newline,shell-var,git,hg,exit,direnv,docker,docker-context,dotenv,root"
            )"

    # Uncomment the following line to automatically clear errors after showing
    # them once. This not only clears the error for powerline-go, but also for
    # everything else you run in that shell. Don't enable this if you're not
    # sure this is what you want.

    set "?"
}

if [ "$TERM" != "linux" ] && [ -f "$GOPATH/bin/powerline-go" ]; then
    PROMPT_COMMAND="_update_ps1_powerline_go; $PROMPT_COMMAND"
fi

while the effect is not the same.
