# X_APP_MODULE_LOAD_FAILED

## Means

an app module failed to load, so the role refused to serve a partial app

## Typical cause

a module under apps/* threw on import or on registration in the container boot; serving without it would drop its routes, actions, policies or jobs

## Fix

`x manifest --json` — names each module that does not load and why; fix it, then restart the role
