Packaging project that has a control rig/modular rig in animation blueprint LogRigVM: Error: Array Index (-1) out of bounds (count 0).

Hello have a project that has a Animation blueprint that has a control rig (connected to the output pose). I can play the project in the editor with no problem. But when I package the project I get the following error.
LogRigVM: Error: Array Index (-1) out of bounds (count 0).
It only happens when I connect the control rig node to the output pose. My control Rig is a Modular Rig. I am not sure if it makes a difference.

Does anyone know why this project does not package/compiles?

Thank you
