gitlab ci pipeline failed deploy ftp - gitlab

Question

I try to build and push my react build folder with gitlab-ci.yml
Build and test passes but deploy failed with this error :
If I do the same script in my locale file, it works !
lftp -e "mirror -R build/ ./test ; quit" -u $USERNAME,$PASSWORD $HOST
mirror: Access failed: /builds/myGitLab/myGitlabProjectName/build: No such file or directory
lftp: MirrorJob.cc:242: void MirrorJob::JobFinished(Job*): Assertion `transfer_count>0' failed.
/bin/bash: line 97: 275 Aborted (core dumped) lftp -e "mirror -R build/ ./test ; quit" -u $USERNAME,$PASSWORD $HOST
ERROR: Job failed: exit code 1
Here is my all yml file :
image: node:13.8
stages:
- build
- test
- deploy
build:
stage: build
script:
- npm install
- npm run build
test:
stage: test
script:

I 've got it ! i was started from a docker image (node) to perform those 3 stages: the build, the test and the deploy but without success but i tried doing an ls-a in the stage deploy I realized that I didn't have the build folder. Because the docker image was recreated each time, so I added artifacts to keep the buid file!
Once the job in the build stage is "done".it keep in a variable buid readable for next job also the deploy !
image: node:13.8
stages:
- build
- test
- deploy
build:
stage: build
script:
- npm install
- npm run build
only:
- master
artifacts:
paths:
- build
test:
stage: test
script:
- yarn
- yarn test
deploy:
stage: deploy
before_script:
- apt-get update -qq
script:
- apt-get install -y -qq lftp
- ls -a
- lftp -e "set ssl:verify-certificate false; mirror --reverse --verbose --delete build/ ./test2 ; quit" -u $USERNAME,$PASSWORD $HOST
only:
- master

Answer 2

I have a part of the answer, but i would like to do something better
Actually, i understood what is going on. On every stage the docker image build then after the build on the test and deploy, there is no more build folder.
I don't know how to persit the docker image witch is node to every stages.
Any help will be welcome.
To make it works i have done every script in one stage this way:
image: node:13.0.1
stages:
- production
build:
stage: production
script:
- npm install
- npm run build
- npm run test
- apt-get update -qq && apt-get install -y -qq lftp
- lftp -e "mirror -R build/ ./test ; quit" -u $USERNAME,$PASSWORD $HOST
only:
- master
