IndexError: no such group

When deploying a Mongo Shell I get the following error when it runs ./hooks/config-changed

Traceback (most recent call last):
  File "./hooks/config-changed", line 1496, in <module>
    retVal = config_changed()
  File "./hooks/config-changed", line 1037, in config_changed
    mongos_port = re.search('--port (\w+)', mongos_cmd_line).group(2)

Here is the output of `config-changed` when debugging:

mongos/0:config-changed % ./hooks/config-changed

I haven't been able to reproduce this. Can you include your deployment configuration for further investigation?

bug is nearly 6 years old with little to no activity - marking invalid (unless we can find a reproducer?).
