[LangSmith SDK] 403 with org-scoped API key: "This API key is org-scoped and requires workspace specification. Please provide 'workspace_id' parameter, or set LANGSMITH_WORKSPACE_ID"

Cause (Documented platform behavior): The server returns error code org_scoped_key_requires_workspace; the SDK maps it to this user error. Other 403s surface as generic "Failed to <METHOD> <path> in LangSmith API." errors. Fix status: documented_behavior Evidence (public sources,

[psycopg2] 'Error: pg_config executable not found.' (and 'libpq-fe.h: No such file or directory') building from source — install libpq dev package / put pg_config on PATH, or use psycopg2-binary

Cause (Documented platform behavior): psycopg2 compiles against libpq; setup.py needs pg_config (usually from libpq-dev) and the libpq headers. Since 2.8 the binary build is only published as the separate psycopg2-binary package. Fix status: documented_behavior Misleading approac

[Langfuse Python SDK] get_prompt: "Cannot specify both version and label at the same time." / "SDK is not correctly initialized. Check the init logs for more details."

Cause (Documented platform behavior): version and label are mutually exclusive selectors; a client created without keys has no resources and get_prompt raises instead of fetching. Fix status: documented_behavior Other error fragments: - SDK is not correctly initialized. Check the

Cause (Documented platform behavior): Organization session-control policy requires periodic reauthentication of user credentials; agents have no TTY to answer challenges. Fix status: documented_behavior Misleading approaches: - Retrying or copying ADC files into sandboxes — copie

[RedisVL SemanticRouter] "Router X has no routes, so there is nothing to match against." / "Semantic routing is only available on Redis version 7.x.x or greater"

Cause (Documented platform behavior): Matching computes max distance threshold across routes (fails on empty list) and uses FT.AGGREGATE with a vector range query, which older Redis Search does not support. Fix status: documented_behavior Other error fragments: - Semantic routing
