Estoy usando Django para back-end y no estoy haciendo front-end

Cuando trato de construir la ventana acoplable, sale este error

node --max-old-space-size=1024 index.js

Pero este código devuelve este error.

 throw err; ^ Error: Cannot find module '/root/mer/index.js' at Function.Module._resolveFilename (internal/modules/cjs/loader.js:636:15) at Function.Module._load (internal/modules/cjs/loader.js:562:25) at Function.Module.runMain (internal/modules/cjs/loader.js:831:12) at startup (internal/bootstrap/node.js:283:19) at bootstrapNodeJSCore (internal/bootstrap/node.js:623:3)

Este es mi Dockerfile para nginx

 FROM node:16-alpine3.11 as web-build COPY webapp /webapp WORKDIR /webapp RUN npm i RUN npm run build FROM nginx:1.19.0-alpine RUN rm /etc/nginx/conf.d/default.conf COPY nginx.conf /etc/nginx/conf.d COPY --from=web-build /webapp/build /usr/var/nginx/webapp

Este Dockerfile para todo el proyecto

 FROM python:3.8.10 ENV PYTHONUNBUFFERED 1 WORKDIR /meded RUN pip install --upgrade pip COPY requirements.txt /meded RUN pip install -r /meded/requirements.txt ADD . /meded/

¿Qué debe hacer el front-end para corregir este error?
