Difference between the command output and the html report

[JCHacking]

Bug Report
When I run mypy I see the following result:
Generated HTML report (via XSLT): C:\Users\jcmencia\PycharmProjects\QA\py_requests\reports\typing\index.html Success: no issues found in 10 source files

But in the html report I get the following line:
self.assertEqual(first=self.__response_data.__str__(), second="RESPONSE", msg="Error verifying Response DTO in a readable format - Incorrect Values")

• Any Types on this line: Explicit (x3)

Is this an expected behavior or as I think it is a bug?
