Hi I tried to replicate and run your echo project but it doesn't work.

forever -w ./built/.

warn:    --minUptime not set. Defaulting to: 1000ms
warn:    --spinSleepTime not set. Your script will exit if it does not stay up for at least 1000ms
error:   Cannot start forever
error:   script C:\Users\luana.fernandes\Documents\Projects\Bot for SharePoint\bot-examples-ts\hello-echo\built does not exist.
npm ERR! code ELIFECYCLE

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
