unable to prepare context: path " " not found for Github Actions Runner - node.js

Question

I am trying to build and tag a docker image in Github Actions runner and am getting this error from the runner
unable to prepare context: path " " not found
Error: Process completed with exit code 1.
I have gone through all other similar issues on StackOverflow and implemented them but still, no way forward.
The interesting thing is, I have other microservices using similar workflow and Dockerfile working perfectly fine.
My workflow

Dockerfile*
FROM node:14 AS base
WORKDIR /app
FROM base AS development
COPY .npmrc .npmrc
COPY package.json ./
RUN npm install --production
RUN cp -R node_modules /tmp/node_modules
RUN npm install
RUN rm -f .npmrc
COPY . .
FROM development AS builder
COPY .npmrc .npmrc
RUN yarn run build
RUN rm -f .npmrc
RUN ls -la

COPY --from=builder /app/package.json ./
ARG APP_API
# set environmental variables
ENV APP_API=$APP_API
EXPOSE ${PORT}
CMD [ "yarn", "start" ]
I guess the problem is coming from the building command or something, these are the different things I have tried
I used --file explicitly with period(.)*
docker build --file Dockerfile \
--build-arg APP_API=$USERS_SERVICE_SECRETS_APP_API \
-t $IMAGE_NAME:$IMAGE_TAG .
echo "::set-output name=image::$IMAGE_NAME:$IMAGE_TAG"
I used only period (.)
docker build \
--build-arg APP_API=$USERS_SERVICE_SECRETS_APP_API \
-t $IMAGE_NAME:$IMAGE_TAG .
echo "::set-output name=image::$IMAGE_NAME:$IMAGE_TAG"
I used relative path for Dockerfile (./Dockerfile)
docker build --file ./Dockerfile \
--build-arg APP_API=$USERS_SERVICE_SECRETS_APP_API \
-t $IMAGE_NAME:$IMAGE_TAG .
echo "::set-output name=image::$IMAGE_NAME:$IMAGE_TAG"
I used relative path for the period (./)
docker build \
--build-arg APP_API=$USERS_SERVICE_SECRETS_APP_API \
-t $IMAGE_NAME:$IMAGE_TAG ./
echo "::set-output name=image::$IMAGE_NAME:$IMAGE_TAG"
I have literally exhausted everything I've read from SO

The problem was basically a white-spacing issue. Nothing could show this. Thanks to This Github answer
