How did you find this issue? I can't figure out what's calling this
function in the first place.
I encountered this while running the tc-testing selftests locally.
The script raised the error:
TypeError: unhashable type: 'list'
The traceback pointed to list_categories(), where a set(map(...))
was being created from the 'category' field.
Since 'category' is a list in the test cases, Python attempts to
insert the list itself into the set, which raises the unhashable
type error. After tracing this, I updated the logic to flatten the
category lists and collect unique category names using set.update().

list_categories() builds a set directly from the 'category'
field of each test case. Since 'category' is a list,
set(map(...)) attempts to insert lists into a set, which
raises:
TypeError: unhashable type: 'list'
Flatten category lists and collect unique category names
using set.update() instead.
