The entity (AAA) has a variable (previousStandstill) with value (BBB) which has a sourceVariableName variable (nextCustomer) with a value (AAA) which is not that entity.
Verify the consistency of your input problem for that sourceVariableName variable.

When I resume my process of solving, it caused an error like above. When I see this problem, the first (AAA) and second (AAA) is different. But in my problem, both (AAA) is the same. What is causing this problem?

Before you call solve() check if your data is correct. So that if AAA.previousStandstill = BBB that then BBB.nextCustomer = AAA.
