Using CML behind a proxy

Hi

Everything running on my GitLab runner must go through a proxy to get anything from the outside world. So, I set the corresponding variables as usual:

stages: 
    - cml_run
    
cml:
    stage: cml_run
    image: dvcorg/cml-py3:latest
    
    script:
        - export http_proxy=proxy:8080
        - export https_proxy=proxy:8080
        - export no_proxy=localhost,127.0.0.1

        - pip3 install -r requirements.txt
        - python train.py > report.md
        
        - cml-publish roc_curve.png --md >> report.md
        - cml-send-comment report.md

However, this results in an error at cml-publish:

$ cml-publish roc_curve.png --md >> report.md
internal/url.js:257
  throw new ERR_INVALID_URL(input);
  ^
TypeError [ERR_INVALID_URL]: Invalid URL: proxy:8080

    at Module.load (internal/modules/cjs/loader.js:879:32) {
  input: 'proxy:8080',
  code: 'ERR_INVALID_URL'

I tried to prefix the variables with http/https since it is complaining about an invalid URL but this just gave me another error:

$ cml-publish roc_curve.png --md >> report.md
FetchError: request to https://asset.cml.dev/ failed, reason: connect ECONNREFUSED 123.45.67.890:443

    at processTicksAndRejections (internal/process/task_queues.js:84:21) {
  type: 'system',
  errno: 'ECONNREFUSED',
  code: 'ECONNREFUSED'

The IP is anonymized above. Any idea how to make CML play nicely with the proxy?

while we had a solution for GL the problem is fundamentally GH. Basically they have the same blocker:
