Hi all,

I have a nextjs app that works fine when run from the command line, but as soon as I add a dockerfile, it fails to find the /app or /pages folder

The structure is
/<MyApp>
/src
/app

And my docker file is as follows

FROM node:20

WORKDIR /app

# Copy package.json and package-lock.json
COPY package*.json ./

# Install dependencies for the project
RUN npm install

# Copy the entire project
COPY . .

# Set the environment variable
ENV NODE_ENV=production

# Build the Next.js application
RUN npm run build

# Expose the application port
EXPOSE 3000

# Start the application
CMD ["npm", "start"]

but I get this error

16.13 > Build error occurred
16.13 Error: > Couldn't find any `pages` or `app` directory. Please create one under the project root

when it tries to execute npm install.

any suggestions?
