System Workbench for STM32

I am looking for how to add UART4 to this aws_demo project I found from here: https://github.com/aws/amazon-freertos/tree/master/demos

I need an interrupt to trigger when receive buffer is full so i can move date into an array.

I tried using the cube generator to generate code for uart4 and the copy into aws demo project in same places.

Seen code in main.c and st32l4xx_it.c that i copied over but here are the errors attached screen shot.
