在以下方法中调用的方法将触发 mypy 起绒 test_get_all_boards: test_get_all_boards invalid syntax mypy(error) . 该方法返回一个布尔值。我只知道现在的语法有什么问题 test_get_all_boards: . 有什么想法吗？

@action(detail=False, methods=["post"])
def try_connection(self, request, *args,**kwargs):
    result = False
    cache = caches["instance_details"]

    if request.data:
        try:
            details = Jira(**request.data)
            if details:
                if cache[details.uuid]['valid_credentials']:
                    result = True
                else test_get_all_boards(details):
                    cache[details.uuid]['valid_credentials'] = True
                    result = True
        except:
            pass

    return Response({"test_result": result}, status=status.HTTP_200_OK)
