Docker and Angular prod `file does not exist` Error on stage build COPY command - docker

Can you see that to help me?
If i build with docker compose command i have this error.
Below are all the steps to build my image and launch my container until the error.

since in the comments you tried to do RUN cd dist && ls which gave you this output :
Step 7/10 : RUN cd dist && ls ---> Running in e8f002e82f3a linking-education-security-front
The steps and dockerfile are perfect. the COPY command from build folder is missing its spell
update this line :
COPY --from=build /usr/src/app/dist/linkingEducationSecurity-front /usr/share/nginx/html
to this :
COPY --from=build /usr/src/app/dist/linking-education-security-front /usr/share/nginx/html
and try rebuilding , this might work.
