OpenCV Error: Assertion failed (abs_max < threshold) in stereoCalibrate

I am trying to run fisheye::stereoCalibrate but I run into an exception for

        CV_Assert(abs_max < threshold); // bad stereo pair

This is an error I get when trying to run multiple images, however if I remove a particular image from the list it does not throw the exception. But on trying to run fisheye::stereoCalibrate for just that image I don't get any exception.

Any suggestions as to why this might be happening?

I have computed the intrinsics for each camera individually with a reproduction error of the order 0.1 , so I don't think that is the issue.
