Failure in Calling Tool to Create Document with AWS Bedrock as LLM Provider

[Henderson11]

Using aws bedrock as the llm provider to call the tool to create a document failed, and the browser network request response part displayed the print information An error occurred.
And I don't have this problem when using openai as provider，Screenshots of actual usage scenarios are as follows:

It is also worth mentioning that in addition to using Provider in the file /lib/ai/index.ts Except for Registry as a model provider, there are no other code changes, and the back-end code is also unchanged. From the screenshots, the model does respond to the tool call request to create a document and renders the document content on the UI interface. on, but it seems that a bug occurs in the second stage: sending the results of the tool call back to llm to generate further summary responses. To a large extent, this bug can be reproduced, as long as you also use the same aws bedrock latest claude 3.5 model as llm provider：
import { experimental_wrapLanguageModel as wrapLanguageModel } from 'ai';
`/lib/ai/index.ts：
import { customMiddleware } from './custom-middleware';
import { models } from './models';
import { registry } from './registry';

export const customModel = (apiIdentifier: string) => {
const model = models.find(m => m.apiIdentifier === apiIdentifier);
if (!model) {
throw new Error(Model with apiIdentifier ${apiIdentifier} not found);
}

return wrapLanguageModel({
model: registry.languageModel(${model.provider}:${model.apiIdentifier}),
middleware: customMiddleware,
});
};

`// Define your models here.

export interface Model {

}

export const models: Array = [
