Error while launching the roslaunch file

Hi, I did the Challenge topics_quiz, but the bot says that there is a mistake on the launch file. But it works fine.

I checked the solution to see if there was any mistake and the solution is different but my approach works, and now I cannot submit one more time.

Can anyone help me with this?

Hi Pedro,

We did advise on the implications of checking the solution, didn’t we? You should have asked for help rather than check the solution to solve the problem.

I’m sorry submitting again after checking the solution is not allowed. If you are sure you code works, then you can move to the next task/unit.

Ok, great, but at the end of the course would i will be able to get the certificate if this unit is no passed since I cannot re-submit the test?

Best regards.
