Pipeline error: "could not load config from forge: %!w()" #279

Could you try to logout of https://ci.codeberg.org/ and login again? then restart a pipeline.

I think the repair repo option in repo settings -> actions
could help

also your config looks strange ...

    commands: >
      # Run the build.

      mkdir build

      cd build

      cmake ..

      make

it would be more common to do:

    commands:
      - mkdir build
      - cd build
      - cmake ..
      - make

The commands format is fine and has always been like this.
It's to allow for wrapping lines of long commands, it's called "folded style block scalar" and is described here:
https://yaml.org/spec/1.2.2/#813-folded-style
and here in more human-readable form: https://stackoverflow.com/a/21699210/1286717

There are no long lines now, but there were some in the past. Anyway, the same format is used in my other project and works just fine there: https://ci.codeberg.org/repos/13633/pipeline/50/config
However, for frugen, the same page is just empty: https://ci.codeberg.org/repos/13632/pipeline/168/config

The .woodpecker.yml file is essentially the same for both projects:
https://codeberg.org/IPMITool/frugen/src/branch/bugfix/refactor-area-sorting/.woodpecker.yml -- broken (for master branch too)
https://codeberg.org/IPMITool/ipmitool/src/branch/master/.woodpecker.yml -- works

I tried pushing repair repo button, and the only change I see sis that now it says pipeline definition not found on the errors page.
It's totally unclear why the definition is 'not found'. If I download the metadata, both the workflow and step fields are empty:

{
  "repo": {
    "id": 13632,
    "name": "frugen",
    "owner": "IPMITool",
    "remote_id": "111660",
    "forge_url": "https://codeberg.org/IPMITool/frugen",
    "clone_url": "https://codeberg.org/IPMITool/frugen.git",
    "clone_url_ssh": "ssh://git@codeberg.org/IPMITool/frugen.git",
    "default_branch": "master",
    "trusted": {}
  },
...
  "workflow": {},
  "step": {},
  "sys": {
    "name": "woodpecker",
    "host": "ci.codeberg.org",
    "url": "https://ci.codeberg.org",
    "version": "3.10.0"
  },
  "forge": {
    "type": "forgejo",
    "url": "https://codeberg.org"
  }
}

I can't understand why it's so and how to fix that. Not much debug info is available regarding the step where Woodpecker pulls the configuration from the repo.

Loggin out and back in also didn't help (I wouldn't expect otherwise because it's clearly a backend, not a UI problem)

Hm that's a different error, that's promising. It might help if you push a commit to the master branch, it's possible it will find the pipeline when doing a clean "run".

You're right! After a new commit to master, it picked up the configuration and ran the build successfully.
I'm now wondering whether or not it will break again when I push to pages branch that doesn't contain .woodpecker.yml

It will not break. It checks the default branch for the woodpecker pipeline.
