Chat ID is required

Error message

Chat ID is required

What it means

Thrown synchronously by GetChatTool._call when chatId is falsy after the params merge. Above the try block at core.ts:605, propagates as a raw Error. zod schema (core.ts:590) marks chatId required. Graph chat IDs are GUID-shaped strings emitted by the /me/chats endpoint.

Solutions

1. Pass chatId explicitly — obtain it first via list_chats if unknown.
2. Fix the params spread order so caller args win over defaults.
3. Catch the propagated Error upstream.
4. Validate chatId is a non-empty string before invoking.

Example fix

// before
const params = { ...arg, ...this.defaultParams }

// after
const params = { ...this.defaultParams, ...arg }

function validateGetChatInput(input: unknown) {
  const { chatId } = (input ?? {}) as any
  if (typeof chatId !== 'string' || !chatId.trim()) throw new Error('chatId required')
  if (!/^[0-9a-f_]{19,}$/i.test(chatId)) console.warn('chatId does not look like a Graph chat id')
}

function isGetChatArgs(x: unknown): x is { chatId: string } {
  return typeof x === 'object' && x !== null &&
    typeof (x as any).chatId === 'string' && (x as any).chatId.trim() !== ''
}

try {
  if (!isGetChatArgs(input)) return { error: 'chatId required' }
  return JSON.parse((await getChatTool.invoke(input)).split(TOOL_ARGS_PREFIX)[0])
} catch (e) {
  return { error: (e as Error).message }
}

When it happens

Trigger: get_chat invoked without chatId; defaultParams clobbering chatId; agent confusing chatId with teamId/channelId/messageId.

Common situations: Agent omitting chatId; defaultParams misconfiguration; UI form cleared; reused defaultParams from a chat tool being applied to a channel tool.
