*gitlab runner docker executor - issue with feature flags in config.toml *

I’ve registered a gitlab-runner with a docker executor for our group on a self-hosted Gitlab 15.7.6 CE.
When I try to set the following feature flags for the runner (as per gitlab-ref) I get the following errors :

FATAL: toml: cannot load TOML value of type string into a Go boolean

or

FATAL: toml: cannot load TOML value of type int64 into a Go boolean

Although the feature flags FF_NETWORK_PER_BUILD; FF_USE_FASTZIP are meant to accept boolean and int.

Below the config.toml :

concurrent = 4
check_interval = 0

[session_server]
  session_timeout = 1800

[[runners]]
  name = "Docker executor runner"
  url = "..."
  id = 2963
  token = "...."
  token_obtained_at = 2023-02-23T12:11:19Z
  token_expires_at = 0001-01-01T00:00:00Z
  executor = "docker"
  [runners.custom_build_dir]
  [runners.feature_flags]
    FF_NETWORK_PER_BUILD = true
    FF_USE_FASTZIP = true
    ARTIFACT_COMPRESSION_LEVEL = "fast"
    CACHE_COMPRESSION_LEVEL = "fast"
  [runners.cache]
    MaxUploadedArchiveSize = 0
    [runners.cache.s3]
    [runners.cache.gcs]
    [runners.cache.azure]
  [runners.docker]
    tls_verify = false
    image = "ubuntu:20.04"
    privileged = false

    • GitLab (Hint: /help) : CE v15.7.6
    • Runner: v15.7.1 - Self-hosted docker executor

  • I’ve already swaped the location of the runner features flags to after the runner cache definition but it didn’t change anything.
    I also tried the suggestion found on the forum and the one present in the documentation on gitlab doc - enable feature flag in runner configuration

Thanks for taking the time to be thorough in your request, it really helps! :blush:
