Please ensure proper configuration' ## Body Cause (Documented platform behavior): The non-dev server verifies a license once at startup; documented requirements are LANGSMITH_API_KEY and/or LANGGRAPH_CLOUD_LICENSE_KEY plus egress to https://beacon.langchain.com (unless air-gapped). One report's stack trace showed the license request URL missing its scheme (malformed endpoint). Fix status: documented_behavior Workaround (not a fix): Use langgraph dev for local testing. Misleading approaches: - Changing LANGSMITH_ENDPOINT to the EU region alone did not resolve the failure in the reported case Limitations: - Which LangSmith plans grant license access is not covered here - Error text is truncated in the reports ('For local development, set a valid ...') Unknowns: - Exact current full error message Other error fragments: - Request URL is missing an 'http://' or 'https://' protocol. Evidence (public sources, summarized; not reproduced by this contributor): - https://github.com/langchain-ai/langgraph/issues/2937 (github_issue, 2025-01-06, reported_symptom): langgraph_api 0.0.15 container crashes with 'License verification failed'; stack trace shows 'Request URL is missing an http:// or https:// protocol'; message tells users to set LANGSMITH_API_KEY (dev) or LANGGRAPH_CLOUD_LICENSE_KEY (prod). - https://github.com/langchain-ai/langgraph/issues/5754 (github_issue, 2025-07-29, reported_symptom): Following the self-hosted docs, the postgres runtime lifespan license check fails (exit code 3) even after setting the EU LANGSMITH_ENDPOINT; docs gap acknowledged via PR. - https://raw.githubusercontent.com/langchain-ai/docs/main/src/langsmith/deploy-standalone-server.mdx (official_docs, 2026-09-27, documented_behavior): Standalone server requires REDIS_URI, DATABASE_URI, LANGSMITH_API_KEY, LANGGRAPH_CLOUD_LICENSE_KEY (authenticates once at startup), LANGSMITH_ENDPOINT without trailing slash for self-hosted LangSmith, and egress to https://beacon.langchain.com for license verification unless air-gapped.
