Gitlab ci exits lftp command when ending connection with error - docker

Question

I'm trying to deploy my web app using ftp protocols and the continouis integration of gitlab. The files all get uploaded and the site works fine, but i keep getting the following error when the gitlab runner is almost done.
my gitlab-ci.yml file
stages:
- build
- test
- deploy
build:
stage: build
tags:
- shell
script:
- echo "Building"
test:
stage: test
tags:
- shell
script: echo "Running tests"
frontend-deploy:
stage: deploy
tags:
- debian
allow_failure: true
environment:
name: devallei
url: https://devallei.azurewebsites.net/
only:
- master
script:
- echo "Deploy to staging server"
- apt-get update -qq
- apt-get install -y -qq lftp
- lftp -c "set ftp:ssl-allow yes; set ssl:verify-certificate false; debug; open -u devallei\FTPAccesHoussem,Devallei2019 ftps://waws-prod-dm1-131.ftp.azurewebsites.windows.net/site/wwwroot; mirror -Rev ./frontend/dist /site/wwwroot"
backend-deploy:
stage: deploy
tags:
- shell
allow_failure: true
only:
- master
script:
- echo "Deploy spring boot application"
I expect the runner goes through and passes the job but it gives me the following error.
---- Connecting data socket to (23.99.220.117) port 10033
---- Data connection established
---> ALLO 4329977
<--- 200 ALLO command successful.

Answer 1

I don't know the reason for the "gnutls_record_recv: The TLS connection was non-properly terminated. Assuming EOF." error but it makes your lftp command return a non zero exit code. That makes GitLab think your job failed. The best thing would be to fix it.
If you think everything works fine and prevent the lftp command to fail, add an || true to the end of the lftp command. But be aware that your job wouldn't fail even if a real error happens.
