Docker Build Issue: No Such File or Directory

Question

I was attempting to dockerize my node project backed by AWS lambda, But when I actually run the file, it gives me the following error.

 => CACHED [build 3/6] COPY . .                                                                                                         0.0s

here is the code for my docker file

FROM node:12 as build

WORKDIR /usr/scr/app
COPY . .
RUN npm install
RUN npm run build:ts
RUN npm prune --production

FROM node:12 as serve

WORKDIR /usr/src/app
COPY --from=build "/usr/src/app/dist/" "/usr/src/app/dist/"
COPY --from=build "/usr/src/app/views/" "/usr/src/app/views/"
COPY --from=build "/usr/src/app/node_modules/" "/usr/src/app/node_modules/"
COPY --from=build "/usr/src/app/package.json" "/usr/src/app/package.json"

EXPOSE 8080
CMD ["node", "dist/app.js"]

as well as the package.json under the same package dockerfile resides

    "name": "express-webserver",
    "version": "1.0.0",
    "description": "",
    "main": "",

        "@types/node": "^17.0.35",
        "typescript": "^4.6.4"
    }
}

The folder structure of my code looks like:

Can anyone help me to see what happened? I can include github link for this project as well if the above info is not adequate. https://github.com/jaydenyen123/typescript-cdk/tree/master/containers/webserver

You've misspelled src in the first WORKDIR statement in the Dockerfile.

WORKDIR /usr/scr/app
