This issue was automatically created by the dependency reviewer bot.

Start by locating the `knex-sample` test and the workflow run linked in the issue, then inspect how the Spanner emulator is expected to be started. Reproduce the failure and trace why no emulator is available at localhost:9010; done means the test runs reliably with the emulator available in CI.
