Abort Signal not forwarded with Bedrock

[IdoPesok]

Description

AI sdk is not using the bedrock library underneath, not fetch, so the abort signal is not forwarded

Code example

import { streamText } from "ai";
import { anthropic } from "@ai-sdk/anthropic";
import { bedrock } from "@ai-sdk/amazon-bedrock";

const main = async () => {
  const abortController = new AbortController();
  const signal = abortController.signal;

  setTimeout(() => {
    abortController.abort();
  }, 2000);

  try {
    const { textStream } = await streamText({
      // model: anthropic("claude-3-5-sonnet-20240620"),
      model: bedrock("anthropic.claude-3-5-sonnet-20240620-v1:0"),
      messages: [
        {
          role: "user",
          content: "write a long poem",
        },
      ],
      abortSignal: signal,
    });

    for await (const message of textStream) {
      console.log(message);
    }
  } catch (e) {
    console.log("got error", e);
  }
};

main();
