Recurring error in Travel, Load, Unload operations from ProcessFlow

I have a recurring problem in my model with the following message:

1631166434770.jpeg

The error "Exception caught in TreeNode::callMemberFunction() c++/dll execution. Throwing... /callbackNode" appears blocking the model usually when the token executes a Travel and Unload operation, to simulate the transport and unloading (flowitem) from a processor A to B by using a portico (The following picture shows an example of the set of instructions in ProcessFlow)

The most disturbing thing about this error is that it occurs in different operations of this set of instructions, distributed throughout the flow: For each simulation the error can occur at different points (Travel, Unloads, Releases operations) of the flow.

Please, Is there anyone who has come up with that mistake on another occasion? Why is it and how can I solve it?

PD: Sorry for not being able to upload the model, but in addition to being a confidential document, the file weighs too much.

Writing of the error in the first picture (it has not the enough size and resolution):
