Bundled connector skill is missing

Error message

Bundled connector skill is missing: ${connector.key}

What it means

applyConnectorSkills resolves the bundled Paperclip skills directory and reads <root>/<connector.skillName>/SKILL.md to attach a connector's skill. If resolvePaperclipSkillsDir cannot locate the bundled skills directory (repo layout changed, package published without skills/, or path moved), it throws 'Bundled connector skill is missing: <key>'.

Solutions

1. Verify the skills/ directory exists relative to the compiled server bundle (server/dist -> ../../../skills)
2. Rebuild/reinstall the server package so bundled skills are included in the artifact
3. Check resolvePaperclipSkillsDir's search roots against your deployment layout; add the correct URL fallback
4. Ensure your container/CI copies skills/ into the image

Example fix

// before (packaging)
# dockerignore excludes skills/
// after
# remove skills/ from .dockerignore / package 'files' exclusion so the bundled catalog ships

import { existsSync } from "node:fs";
const skillsRoot = path.resolve(serverDist, "../../../skills");
if (!existsSync(path.join(skillsRoot, connector.skillName, "SKILL.md"))) {
  throw new Error(`Deployment missing bundled skill: ${connector.skillName}`);
}

try {
  await connectorRuntime.connectorConfig(companyId, key);
} catch (e) {
  if (e instanceof Error && e.message.startsWith("Bundled connector skill is missing")) {
    // fall back to remote/catalog skill resolution or surface a deploy error
  }
  throw e;
}

When it happens

Trigger: Calling connectorRuntime.configured/disconnected/before/after/connectorConfig/runtimeSkillConfig for a connector whose bundled skills directory cannot be resolved from the running server bundle; skills/ folder absent relative to the compiled server package.

Common situations: Running the server from a packed/installed package that excluded the skills directory; refactors moving server build output so ../../../../skills no longer resolves; partial checkouts or Docker images missing the skills folder.
