The object's EPD QuantityType is Undefined and cannot be evaluated Error

I am using the LCA toolkit and I can not calculate the EPD and this error shows: Warning: Compute.RunCaller operation failed. The object's EPD QuantityType is Undefined and cannot be evaluated.

How can I solve this?

Start by reproducing the LCA calculation that fails in Compute.RunCaller and inspect how the object's EPD QuantityType is handled. Done means the calculation no longer fails with the Undefined QuantityType warning; the issue names no files or tests, so the relevant implementation and coverage must first be located.
