"error: process ID out of range" when in git directories

[Rush]

I am getting this error whenever I enter a git directory using the hydro shell:

 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).

Is hydro_fetch enabled? If so, maybe there's something misplaced in your config.fish. Hydro doesn't use ps.

Are you also running the latest version of Fish?

Yes latest but you could be right that maybe I had something misplaced. Unfortunately the easiest solution was to remove hydro and write my own prompt. Sorry for the confusion.
