Example Code

const chatModel = new ChatBedrockConverse({
    model: modelOptions.model,
    region: modelOptions.region,
    temperature: config.temperature,
    maxTokens: config.max_tokens,
    topP: config.top_p,
    streaming: true,
    maxRetries: 10,
  });

Description

Does ChatBedrockConverse have a built-in retry mechanism?

I used ChatBedrockConverse with maxRetries=10, but still receive a lot of 503 errors from Bedrock.
I'm not sure whether maxRetries is used for a built-in retry mechanism, or I have to implement my own logic.
Additionally, if ChatBedrockConverse already handles the retry, when does it log the error returned from Bedrock? With each error response, or after the final failed retry?
