HSX_E_DEV_MANAGED_START

Managed dev session failed to start.

What this error means

The detached hs-x dev process did not reach the ready state.

When this error stops a command, hs-x exits with code 1. With --json, the failure is reported as a structured error whose code field is HSX_E_DEV_MANAGED_START — stable to match on in scripts and agents.

Likely causes

  • Project validation failed
  • A required port is occupied
  • The child process exited

How to fix it

  • Read the stderrPath returned in the error payload
  • Resolve the startup error and run hs-x dev start again
