On a self-hosted Stormkit instance (v2026.08.02.1), followed the Application runtime docs for a Go binary to the letter: build the binary to .stormkit/server/app, set the output folder to .stormkit, and set the Start command to ./app. Every deployment failed with Error: cannot auto detect serverless entry file: expecting a file name called (index|server).{js,mjs,cjs}. The presence of the server/ subfolder was routing the deployment into serverless/SSR entry detection, and the Start command was never consulted, so the documented config could not succeed.

This was a platform bug, fixed upstream in PR #410. The bundling logic was treating any server/ subfolder in the output as a serverless entry and skipping the Start command entirely. The fix makes the Start command take effect so a server/ folder no longer hijacks entry detection. If you are self-hosting, upgrade your instance to a release after 2026-08-03 that includes the fix; the documented config (binary at .stormkit/server/app, Start command ./app) then deploys normally.
