Deploy a containerized Lucidchart integration service that manages diagram documents, manipulates shapes and connectors programmatically, and synchronizes visual collaboration data through the Lucid API. This skill covers Docker multi-stage builds for the Lucid SDK, OAuth2 token configuration, health checks that validate document API access, and rolling deployments with safe diagram state preservation during updates.

| Issue | Cause | Fix |
|---|---|---|
| 403 on document access | OAuth2 scopes missing lucidchart.document.content |
Re-authorize with required scopes in Lucid developer portal |
| Container OOM killed | Large diagram rendering exceeds memory | Increase memory limit to 1GB with --memory=1g for complex documents |
| Token refresh failures | Expired LUCID_CLIENT_SECRET or clock skew |
Regenerate client credentials and verify server time sync (NTP) |
| Health check timeout | Rate limiting on /v1/documents endpoint |
Increase HEALTHCHECK --timeout to 15s; cache document count locally |
| Shape API 422 errors | Invalid page or layer ID in diagram mutations | Validate document structure with GET /v1/documents/{id}/pages before writes |
