Hello, I am studying DevAcademy Lesson 4 - Data exchange in Bluetooth LE, specifically Exercise 3 using the nRF5340DK. While attempting to build the corresponding Git code (v2.8.x-v2.7.0/l4/l4_e3_sol) to upload it to the nRF5340DK, I encountered the following error. I am unable to determine the cause.
