In the middleware doStream, in the incoming params, maxRetries is default value

[adolphnov]

Description

In the middleware doStream, the obtained maxRetries is incorrect. The parameter obtained from prepareCallSettings does not include maxRetries：

fn: async (doStreamSpan3) => ({
              startTimestampMs: now2(),
              // get before the call
              doStreamSpan: doStreamSpan3,
              result: await model.doStream({
                mode,
                ...prepareCallSettings(settings),
                inputFormat: promptFormat,
                prompt: promptMessages,
                providerMetadata,
                abortSignal,
                headers
              })
            })

Check the streamText definition, settings do not carry user-defined maxRetries:

async function streamText({
  model,
  tools,
  toolChoice,
  system,
  prompt,
  messages,
  maxRetries,
  abortSignal,
  headers,
  maxToolRoundtrips = 0,
  maxSteps = maxToolRoundtrips != null ? maxToolRoundtrips + 1 : 1,
  experimental_continueSteps: continueSteps = false,
  experimental_telemetry: telemetry,
  experimental_providerMetadata: providerMetadata,
  experimental_toolCallStreaming: toolCallStreaming = false,
  experimental_activeTools: activeTools,
  onChunk,
  onFinish,
  onStepFinish,
  _internal: {
    now: now2 = now,
    generateId: generateId3 = originalGenerateId4,
    currentDate = () => /* @__PURE__ */ new Date()
  } = {},
  ...settings
}) {

Code example

return {
        wrapGenerate: async ({ doGenerate, params, model }) => {
            log.info('doGenerate called');
            log.debug(`params: ${JSON.stringify(params, null, 2)}`);
            log.info(`provider: ${model.provider}, modelId: ${model.modelId} `);
            const logs = getLogSingleton(config);
            activeTools.length > 0 ? logs.tool.model = model.modelId : logs.chat.model.push(model.modelId);
            const result = await doGenerate();
            log.info(`generated text: ${result.text}`);
            return result;
        },
...
}

maxRetries should not be exposed to the middleware. It is handled on the generateText / streamText level.

Got it. It is suggested to modify the signature here.
