"Invoke the API Service using generated client SDK" Mission Problem

I complete every task as shown in the documentation but when I click “Get Instruction, Get Item, Get Items, Purchase” links nothing invoked.

Note: I use javascript to complete this mission.

Hello @Mohammad_Rabby_Hauq ,

could you please record a video of your progress through this task? This will give us more insight into where exactly something might have gone wrong.

Regards,
Stanislaw
