When I execute the code in the platform it shows the following error

Go over the code pecause I just executed it in Robot Ignite and it worked without issue. Here I leave yo two main files that should be used:

If you dont find the issue plese post your code, mybe there is something wrong in it or your have sourced something wrong… There coudl be man things so have a look at this solution first.
