echo_app fails with error nitialization error occurred for pubsub (pubsub.redis/v1)

Getting the following errors when trying to compile and run the example application.

Start by reproducing the echo_app compile-and-run failure and inspect how the pubsub.redis/v1 component connects to Redis at localhost:6379. Confirm whether the example's Redis dependency is running or its configuration is incorrect; done means the app starts without the INIT_COMPONENT_FAILURE connection-refused error.
