=> ERROR [deps 4/5] COPY package.json npm.lock ./ tengo este problema, como lo podria solucionar

Me sale un error en el RUN npm run build, a alguien le paso?

executor failed running [/bin/sh -c npm run build]: exit code: 1

@Benji-Mtz A mi me salió lo mismo pero cuando lo instale la primera vez y lo solucione cambiando la versión de la siguiente manera:

yarn add --dev @types/[email protected] o el equivalente en npm.

Hola saben como puedo solucionar este error?

=> ERROR [deps 4/5] COPY package.json npm.lock ./
Para este error, borrar el yarn.lock si es que no lo estan utilizando a mi me funciono

docker build -t nextjs-initial .
docker run --name=next-app -p 3000:3000 nextjs-initial

Es importante revisar qué manejador de paquetes se está empleando, en mi caso la configuración es la siguiente para npm:
