It's important to remember that the example code used in this course was designed to support learning a specific aspect of Temporal, not to serve as a ready-to-use template for implementing a production system.
For the exercises, make sure to run temporal server start-dev --ui-port 8080 --db-filename clusterdata.db in one terminal to start the Temporal server. For more details on this command, please refer to the Setting up a Local Development Environment chapter in the course. Note: If you're using the Gitpod environment to run this exercise, you can skip this step.
