Error in value[[3L]](cond) : version 'x.y.z' is invalid for package 'callr'

Thanks for automating this task and for giving it a nice UI! I learned of it via the responses to this tweet.

The package I'm interested in is callr. Not sure if that has anything do with callr specifically, but I consistently see something like this:

Error in value[[3L]](cond) : 
  version '3.2.0' is invalid for package 'callr'

The specific package version reported varies according to my exact call, but so far every call has lead to some output of that sort. And yet it seems like I eventually get usable results. And affected version sure seems to be legit. Not sure what's going on.

Example:

> when_api_same("callr::r", report = "full")
