[ymgupta]

Summary

The Things Stack components are inherently stateless and depend on the underlying Postgres and Redis databases to store the data. The first time The Things Stack is started, it requires initializing the database of the Identity Server. Without the Identity server initialization and execution of the further steps will lead to the database error. Please add the error Database error and resolution to the Troubleshooting Installation documentation
