polybar-scripts: [info-softwarecounter.py] process ID out of range for gnome-builder

I’ve noticed that I have an error message when I open gnome-builder which says error: process ID out of range, this is strange because according to /proc/sys/kernel/pid_max:

$ cat /proc/sys/kernel/pid_max
4194304

$ ps aux | grep "builder\|^U"
USER         PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND

The process ID is in range, so could this be a problem with subprocess python module? I would like in fact to add gnome-builder to the vims tuple in the dict, but it has not any effect because of the error message. This is the traceback

error: process ID out of range

Usage:
 ps [options]

 Try 'ps --help <simple|list|output|threads|misc|all>'
  or 'ps --help <s|l|o|t|m|a>'
 for additional help text.

For more details see ps(1).
