my query returns the error:

  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/jsonpath_ng/jsonpath.py", line 625, in _find_base
    return [DatumInContext(datum.value[self.index], path=self, context=datum)]
KeyError: 0

In the original file there are many instances like I provided and when I go with wildcard It works fine and I can go for each one

Have you tried using $.units[0].ID instead?
