No classes found in TypeDoc output

Error message

No classes found in TypeDoc output

What it means

Internal docs-generation script error: TypeDoc ran but its project reflection has no children, meaning it parsed no exported classes. This indicates an empty/broken parse of the source, not a problem with the SDK runtime.

Solutions

1. Verify the TypeDoc entryPointStrategy/entryPoints config still points at real source files
2. Build the package first (pnpm build:packages) so generated/compiled surfaces exist
3. Check the pinned TypeDoc version hasn't drifted; re-pin if a major bump changed output
4. Debug runTypeDoc() output to confirm the project reflection is populated

const project = await runTypeDoc();
if (!project.children?.length) failFast('entry points misconfigured');

try { await main(); } catch (e) { if (e.message === 'No classes found in TypeDoc output') { console.error('check TypeDoc entryPoints'); process.exit(1); } }

When it happens

Trigger: Running scripts/generate-docs.ts when TypeDoc entry points are misconfigured, the build/entry files are missing, or TypeDoc version changes yield a different project shape.

Common situations: CI docs job after a refactor moved entry points; TypeDoc major-version bump changing output structure; running the script before building the package.
