SvelteKit: Error de ‘npm run build’ en AWS CodeBuild.

Tengo una aplicación SvelteKit que estoy desplegando utilizando AWS CodePipeline.

Mi pipeline se activa en los impulsos de CodeCommit. Pero CodeBuild falla con los siguientes mensajes de error:

“`npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! project-title@0.0.1 build: <code>svelte-kit build</code>
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the project-title@0.0.1 build script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
[Container] 2021/11/30 14:45:25 Command did not exit successfully npm run build exit status 1

<pre><code><br />Intenté clonar el repositorio y compilarlo en un entorno limpio en mi PC y se construyó sin errores. No puedo reproducir el problema fuera de CodeBuild.
