AssertionError in existing test

Describe the bug

AssertionError occurs in the existing tests.

I have forked this repo and raised a PR with some changes related to LD support. You can view the PR here:
#695

There has been no changes I've made in the tests as such. But still it throws an AssertionError. Below is the error logs:

src/reporter/tests/test_aggregation_different_attribute_types.py:401: AssertionError

Update: I made a small change in the code and pushed it to the repo. That ran the circleci tests and all the tests were passing as usual.

PS: idk why I got this error that one time.
