How comes a GitLab CI/CD job cant' find its artifacts?

Question

In the Open Source ventilator project, we aim to provide those who focus on testing with a ready-to-go flash file for the Arduino controller board.

While the binaries seem to be there, for some reason the CI job can't pickup the artifacts.

What is happening:

• a CI/CD pipeline creates two files which can be listed using find
• in the next step, this pipeline reports it can't find these artifacts. It says, "no matching files/no files to upload".

What's the error and how to fix/troubleshoot? Why does this job end up as successful?

CI job definition:

compile:
  stage: build
  tags:
    - docker
  script:
    -  |

        git clone -b ci-gh https://github.com/mattd3v/Open-Source-Ventilator.git
        cd Open-Source-Ventilator/OpenSourceVentilator/
        arduino-cli compile --warnings all --fqbn arduino:avr:uno -o osv-controller-uno.bin OpenSourceVentilator.ino
        find .
  artifacts:
    paths:
    - ./osv-controller-uno.bin.hex
    - ./osv-controller-uno.bin.elf

Pipeline output:

As Casey Vega commented: provide the complete path.
