Show powershell errors in flask-wtf web form

[robertkwild]

ok im doing this

@app.route('/password', methods=['GET', 'POST'])
def password():
    form = PasswordForm()
    if request.method == 'POST' and form.validate():
        try:
            result = subprocess.run(f'powershell.exe $cred = Import-CliXml -Path C:\\python\\cred.xml; Set-ADAccountPassword -Credential $cred -Identity {form.un.data} -OldPassword (ConvertTo-SecureString -AsPlainText {form.op.data} -Force) -NewPassword (ConvertTo-SecureString -AsPlainText {form.cnp.data} -Force) -Server {form.dom.data}', capture_output=True, text=True, shell=False)
            print("STDOUT:", result.stdout)
            print("STDERR:", result.stderr)
        except:
            print("something went wrong")
        return '<h1>The username is {}. The old password is {}. the new password is {}. changing for domain {}'.format(form.un.data, form.op.data, form.cnp.data, form.dom.data)
    return render_template('password.html', form=form)

if __name__ == '__main__':
    app.run(debug=True)

but when the subprocess command fails its not showing the print message in except

also if the sub process command fails i dont want it to display that return line ie to show what you typed in username old password, new password, domain
