Help required with timer user stories of 25+5 clock

FCC tests 12. 13. 14, 15 are not passing even though I can see that my timer reaches 00:00 and it toggles between session and break.
Please help !

Challenge: Build a 25 + 5 Clock

Link to the challenge:

Perhaps the string (break/session) should change when the time changes from 00:01 to 00:00.

Thank you for the suggestion @ptola :slight_smile:.
According to the demo, the string should change the next second after the timer becomes 00:00. Not just that, there is an error which says, the timer has not reached 00:00, that is not what I am not able to understand.
