Topic Quiz mistake 7.9 Actions Quiz

Hi I believe I was incorrectly marked for this section

Weirdly enough when I was last marked, I received marks for having the bot launch the file correctly. Just unsure why it isn’t the case this time round.

Hello @jeffrey.jahja7 ,

I just checked your latest correction logs. When launching the action client, the following error appears:

[server-1] e[31m[ERROR] [1747137421.726183291] [distance_action_server]: Error raised in execute callback: type object 'Distance' has no attribute 'STATUS_SUCCEEDED'e[0m

[server-1] AttributeError: type object 'Distance' has no attribute 'STATUS_SUCCEEDED'

This is why the grader is failing you at this stage.

Best,

Hi @albertoezquerro ,

What do you think is the best solution to this? I launched it on my own and it worked.

[albertoezquerro]

It’s an error in your code, exactly in this line:

if nav_result.status == Distance.STATUS_SUCCEEDED:

The error is: AttributeError: type object 'Distance' has no attribute 'STATUS_SUCCEEDED'

So you need to fix the error in your code.

Best,
