ID 486099 - Keyframes cannot be added after an error occurs when frames are calculated behind the camera in a Reconcile3D node.

Problem summary
Keyframes cannot be added after an error occurs when frames are calculated behind the camera in a Reconcile3D node.

Customer reported version
nuke.12.2v7

Customer reported platform
centos7

Steps to reproduce
1) In Nuke, create a Camera and an Axis node.
2) Adjust knob parameters for their positions.
3) Add a Reconcile3D node, attaching the Camera and Axis nodes.
4) Calculate the node by adding keyframes.

Expected behavior
The node should continue to add keyframes after an error occurs.

Actual behavior
The Reconcile3D node no longer adds keyframes after an error occurs.

Workaround
Ensuring that the calculated frames are in front of the camera allows the keyframes to continue.
