Environment & Version information

package projectile-20210607.1513 package ag-20201031.2202

executable ag version 2.1.0 (I know this is rather old, but I suspect the error is not related to this, but rather to the communication between the two Emacs packages projectile and ag.)

Projectile 20210607.1513

Emacs version

GNU Emacs 27.1

Operating system

CentOS 6 (I know this is rather old, but ... see above.)

Actually I now tried just using the ag function in ag.el - and I get the same error (see issue #173, so I think this is not a problem in Projectile.

However, it still breaks Projectile's ag functionality...
