Error message

No workspace agent provider set. Please set your agent provider in the workspace's settings

What it means

Fallback branch in the agent setup check: none of the known provider cases matched the workspace's configured agent provider (or no provider was set at all), so the agent subsystem has no LLM backend to run against and the setup check rejects the configuration.

Solutions

1. Open the workspace settings and select an agent provider and model.

When it happens

Trigger: No agent provider was configured for the workspace.

Common situations: This error is raised at runtime in server/utils/agents/index.js. It occurs when the required configuration for this provider is missing or invalid (unset environment variables, empty API key or base path), when the external service is unreachable or returns an unexpected response, or when invalid input reaches the call site. To prevent it, validate the relevant provider settings and environment variables at startup and confirm the service is reachable before this code path executes.
