_InstantiatorFn.__call__() missing 1 required keyword-only argument: 'applied_instantiation_links'

I encountered a package compatibility error trying to run the code.

...

    return instantiator(class_type, *args, **kwargs)
TypeError: _InstantiatorFn.__call__() missing 1 required keyword-only argument: 'applied_instantiation_links'

I admit that I am trying to run this out of the box with little modification, but I am hoping that someone can suggest an easy fix. I am not sure where to begin to troubleshoot!

Thanks,
Drew

For the record, I "solved" this problem (at least temporarily) by adding a bogus keyword to _common.ClassInstantiator.__call__ in the jsonargparse package:
return instantiator(class_type, *args, applied_instantiation_links = {}, **kwargs)
I may later discover that this is not a good idea, but it seems to be working.

Thanks for your attention. This seems to be related to the versions of the packages. We use the previous code version of ProbTS. You can refer to the issues in their repository to search for a permanent solution.
