HSX_E_INPUT_BUN_REQUIRED

Bun is required for Cloudflare deploys.

What this error means

A deploy that targets Cloudflare needs Bun 1.1 or newer, but no compatible `bun` executable was available on PATH.

When this error stops a command, hs-x exits with code 10. With --json, the failure is reported as a structured error whose code field is HSX_E_INPUT_BUN_REQUIRED — stable to match on in scripts and agents.

Likely causes

  • Bun is not installed
  • Bun is installed but not available on PATH
  • Bun is older than 1.1

How to fix it

Still stuck? Re-run the command with --debug for the wire-level detail, or hs-x doctor to check accounts, link state, and connectivity in one pass.
