Hi, I am trying to get my Next.js app inside my turborepo deployed with docker, but it keeps saying the standalone folder is not found.

Output is set to 'standalone' in nextjs.config.js

Dockerfile:

FROM node:alpine AS base
 
ENV PNPM_HOME="/pnpm"
ENV PATH="$PNPM_HOME:$PATH"
RUN corepack enable

FROM base AS builder
RUN apk update
RUN apk add --no-cache libc6-compat

# Set working directory
WORKDIR /app
# Replace <your-major-version> with the major version installed in your repository. For example:
# RUN yarn global add turbo@^2
RUN pnpm add -g turbo@^2
COPY . .
 
# Generate a partial monorepo with a pruned lockfile for a target workspace.
# Assuming "web" is the name entered in the project's package.json: { name: "web" }
RUN turbo prune web --docker
 
# Add lockfile and package.json's of isolated subworkspace
FROM base AS installer
RUN apk update
RUN apk add --no-cache libc6-compat
WORKDIR /app
 
# First install the dependencies (as they change less often)
COPY --from=builder /app/out/json/ .
RUN pnpm install
 
# Build the project
COPY --from=builder /app/out/full/ .
RUN pnpm turbo run build --filter=web...
 
FROM base AS runner
WORKDIR /app
 
# Don't run production as root
RUN addgroup --system --gid 1001 nodejs
RUN adduser --system --uid 1001 nextjs
