unexpected first-party source

Error message

unexpected first-party source: {spec}

What it means

scripts/sync-marketplace.py snapshots the first-party plugin marketplace. Every plugin entry's `source` in marketplace.json must be a `path:` spec pointing into the repository; anything else is unexpected because the marketplace only ships first-party, in-repo plugins. It exits via SystemExit when it encounters a non-path source spec.

Solutions

  1. Open marketplace.json and find the plugin whose source is not `path:`.
  2. Change it to a `path:relative/dir` spec pointing at the plugin's directory in the repo.
  3. If the plugin is external, host its bundle inside the marketplace repo instead.
  4. Re-run scripts/sync-marketplace.py.

Example fix

// before (marketplace.json)
{"name": "x", "source": "git+https://github.com/me/x"}
// after
{"name": "x", "source": "path:plugins/x"}
Defensive patterns

Strategy: validation

Validate before calling

import json
catalog = json.load(open('marketplace.json'))
for c in catalog['plugins']:
    assert c['source'].startswith('path:'), f"{c['name']} not a path source"

Try / catch

try:
    subprocess.run(['python3','scripts/sync-marketplace.py','--check'], check=True)
except SystemExit as e:
    print('marketplace source error:', e)

Prevention

When it happens

Trigger: A marketplace.json plugin entry uses a `git:`, `https:`, or bare source spec; someone edits marketplace.json to point at an external plugin.

Common situations: Copying a plugin entry from a third-party marketplace catalog; hand-editing marketplace.json to reference an external repo; a tool generating remote-source entries.
