Service Quiz error

Hi I have been trying to solve the Service Quiz at the end of Module 6 but I am stuck.
I created the package and launch files and python codes for the first part of the quiz but I keep getting an error stating:
[ERROR] [1631089715.685576, 3601.280000]: Error processing request: ‘EmptyRequest’ object has no attribute ‘repetitions’

Can you please help me with this.

Hi, just check the structure of your custom message which you created for the service. Also, when your face these problems, please share the code so that someone can analyze your program to debug it. The structure of the message should be like this

. If it is still not resolved, then please share your service server and service client code. Cheers.
