Exercise Tracker, cant pass test 5 and 6

Hello everybody,

I am trying to solve the exercise Tracker, but i have no clue what i should do to get it right. My file is passing the test 1 - 4 and 7.

I also looked into the test code on

but i couldn’t find the problem. Im unsure, if my response has the right format.
Below is a sample of the response for test 5/6.

username: ‘fcc_test_16135859219’,
_id: 602d5e0381dff5026fb55f4d,
log: [
{ description: ‘test’, duration: ‘60’, date: ‘Mon Jan 01 1990’ },
{ description: ‘test’, duration: ‘60’, date: ‘Tue Jan 02 1990’ }
count: 2

Also i dont know how i can see/find the errors of my repl project after i submitted my solution. Thats why i have no clue what to do next.
