Dockerfile works correctly in local, but Don't work in CircleCI

I want to Do CI/CD with CircleCI to ECR, ECS.

Dockerfiles works correctly in local with docker-compose. but, I am getting the following error in CircleCI.

COPY failed: stat /var/lib/docker/tmp/docker-builder505910231/b-plus-app/build: no such file or directory

Here is the relevant code where the error occurred.

↓Dockerfile(react)↓

FROM node:14.17-alpine
WORKDIR /usr/src/app

COPY . /usr/src/app

RUN rm -r -f b-plus-app/build && cd b-plus-app \
  && rm -r -f node_modules && npm i && npm run build

↓Dockerfile(nginx)↓

FROM nginx:1.15.8

RUN rm -f /etc/nginx/conf.d/*
RUN rm -r -f /usr/share/nginx/html 


#Stop Here
COPY b-plus-app/build  /var/www
COPY prod_conf/ /etc/nginx/conf.d/

CMD /usr/sbin/nginx -g 'daemon off;' -c /etc/nginx/nginx.conf
