unauthorized: authentication required error while creating docker nodejs image

  build, docker, node.js

I am new to docker and trying to build docker image for my nodejs project.

This is my docker file

FROM node:10
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
EXPOSE 8443
CMD ["node", "index.js"]

Command used to build the image

docker build -r test-project .

It is giving unauthorized: authentication required after few minutes

I have done authentication before starting build using

docker login -u <username>

Please help with authentication error while building docker image.
