generateText does not automatically use the tool results and incorporate them into the final output.

Hi Experts

I created a simple agent that does tool calling .

export function agent(topic: string) { return generateText({ model: my_model, // prompt:xxxxx, tools: { my_tool: { }, }); }
the tool results is what I expect when looking at the log. But here is how the final output looks like:

DefaultGenerateTextResult { text: "", files: [], reasoning: undefined, reasoningDetails: [], toolCalls: [ { type: "tool-call", toolCallId: "call_xUajNp7joQyaAIphn1WxMjEu", toolName: "deepResearch", args: [Object ...], } ], toolResults: [ { type: "tool-result", toolCallId: "call_xUajNp7joQyaAIphn1WxMjEu", toolName: "deepResearch", args: [Object ...], result: XXXXXXXXX } ], finishReason: "tool-calls", usage: { promptTokens: 116, completionTokens: 20, totalTokens: 136, }, warnings: [], request: {yyyyy}, response: {}, steps: [ { stepType: "initial", text: "", reasoning: undefined, reasoningDetails: [], files: [], sources: [], toolCalls: [ [Object ...] ], toolResults: [ [Object ...] ], finishReason: "tool-calls", usage: [Object ...], warnings: [], logprobs: undefined, request: [Object ...], response: [Object ...], providerMetadata: [Object ...], experimental_providerMetadata: [Object ...], isContinued: false, } ], experimental_providerMetadata: { openai: { reasoningTokens: 0, acceptedPredictionTokens: 0, rejectedPredictionTokens: 0, cachedPromptTokens: 0, }, }, providerMetadata: { openai: { reasoningTokens: 0, acceptedPredictionTokens: 0, rejectedPredictionTokens: 0, cachedPromptTokens: 0, }, }, logprobs: undefined, outputResolver: [Function: outputResolver], sources: [], experimental_output: [Getter], }

Based on the behavior you’re seeing, it looks like the tool’s final result is actually being stored in the toolResults field (result: XXXXXXXXX) rather than in the top-level text field ( text: ""). is this expected ? Shouldn't generateText automatically use the tool results and incorporate them into the final output ?

What is your generateText call? did you configure maxSteps?

setting maxSteps to 2 solved the problem, I initially played with this but not sure why I missed it, thanks again for your reply!
