fails to parse assignment of list filtered with 'list' built-in filter

[MikeCook9994]

I have this one line of jinja2 that contains no html. It is a valid template that jinja2 is able to parse. I can additionally write some additional parts of the template to actually use the assigned value here and am able to render it

{% set filteredList = ThisIsAListOfObjects | selectattr("SomeProperty", "equalto", "SomeValue") | list %}

When inferring this I receive the following stack trace:

Traceback (most recent call last):
  File "C:\Python34\lib\site-packages\jinja2schema\visitors\expr.py", line 116, in meet
    merge(self.predicted_struct, actual_struct)

    raise MergeException(fst, snd)
jinja2schema.exceptions.MergeException: unnamed variable (used as scalar on lines 1) conflicts with unnamed variable (used as list on lines: )

During handling of the above exception, another exception occurred:

Here is the AST jinja2 gives from parsing:
