Python-Click Console Output to Logfile

Question

I would like to capture the Python-click Console output in order to write it into a logfile for example when an argument was not specified. Is there a way I can capture the console output from click. I have tried it with this code:

@click.group(cls=DefaultGroup, default="subcmd", default_if_no_args=True)
@click.option('--verbose', '-v', is_flag=True, help="Increase output verbosity level")
@click.pass_context
def main(ctx, verbose):
    ctx.obj["verbose"] = verbose
    lines = click.get_text_stream("stderr").readlines()
    #further code to write the stderr lines into to the logfile

@main.command("subcmd", context_settings=dict(allow_extra_args=True,))
@click.argument('arg1', required=True, default="Value1", type=click.Choice(['Value1', 'Value2']))
@click.argument('arg2', required=True)
@click.pass_context
def subCmd(ctx, arg1, arg2):
    pass

if __name__ == "__main__":
    main(obj={})

Unfortunately, this gives me an error
