Frontend test failure


I am a new user to Redash. I have cloned the latest Redash and tried to run Redash frontend test locally step by step following developer guide. But all the tests fail due to the similar reason:

I also tried to run a single test visually. It seems the test fails to login in although it returns 200 when hitting /login API.

I can’t find any solution in the forum. Has anyone happened to have similar issue? Or Is there anything I am missing in the frontend test setup?
