Research direction

Compare src/agents/productionAgent.ts at lines 355-362 with src/agents/scriptAgent.ts at lines 481-493, starting with how the script path determines bypassUser. Verify with an activated Employee Agent that sf agent preview creates a session and exchanges messages without the invalid-user error.

Description

area:afdx bug owned by another team

sf agent preview can never start a session with a published Employee Agent:

Error - Bad Request: Invalid user ID provided on start session: 

productionAgent.ts hardcodes bypassUser: true:

https://github.com/forcedotcom/agents/blob/597dad0fca74c81aa8fa3a89b1718aa65c6bfbde/src/agents/productionAgent.ts#L355-L362

Per the Agent API reference, true means "use the user associated with the agent" and is only for the client credentials flow; the default is false. Employee Agents have no agent user (BotDefinition.BotUserId is null by design), so the server resolves an empty user ID.

Same org, same agent, same JWT, varying only bypassUser:

body result
bypassUser: true (what the CLI sends) 400 Invalid user ID provided on start session:
bypassUser: false 200, session created, messages exchanged
userId (explicit) 400 Unrecognized field "userId"

The Agent Script path in the same package already handles this:

https://github.com/forcedotcom/agents/blob/597dad0fca74c81aa8fa3a89b1718aa65c6bfbde/src/agents/scriptAgent.ts#L481-L493

The production (published agent) path is missing the equivalent.

Repro: deploy and activate any Employee Agent (reproduced with coral-cloud), then sf agent preview --api-name <agent>. The agent is listed as (Published), so discovery works — only the session start fails.

Suggested fix: derive bypassUser in productionAgent.ts instead of hardcoding it, mirroring scriptAgent.ts.

Workaround: none from the CLI (no flag or env var). Calling the Agent API directly with bypassUser: false works.

Env: @salesforce/cli 2.143.6, @salesforce/plugin-agent 1.44.4, @salesforce/agents 1.10.2, Node 24.18.0, macOS arm64, Agentforce Developer Edition (API v67.0)
