Tell us what’s happening:
All testcases pass except testcase 19. The error I get is:
“The height of each bar on the create_spend_chart chart should be rounded down to the nearest 10.”
I think I calculated the percenteges correctly, so I don’t know where the problem is.
In the console I get the following error:
{message: ‘Unspecified AssertionError’, showDiff: false, actual: null, expected: undefined, stack: ‘AssertionError: Unspecified AssertionError\n at …t-runner/9.0.1/python-test-evaluator.js:2:157407)’}
Need hlp
