Zephyr SDK and OpenOCD on Mac (intel)

Trying again to resolve issue with uploading firmware of Zephyr SDK example to a SWAN via OpenOCD and STLink V3. I notice this error after Zephyr build within the container and wonder if the source of the issue and how to resolve?

Snippet from “main.c”, #include <zephyr/drivers/gpio.h> is marked as error:

Additional symptom. Upon deleting Container, Images, Volumes and reloading and reopening the Docker Container, a CMake error occurs related to Board Definition?
