## Background

This pull request adds the ability for clients to resume an ongoing chat
generation stream after a network disconnect.

## Summary

This pull request adds support for the `useChat` hook to resume an
ongoing chat generation stream by exposing `experimental_resume()` that
can be called by any client, typically during the initial mount of the
hook.

The `experimental_resume` function makes a `GET` request to the api
endpoint you've initialized the hook with (or `/api/chat` by default)
and streams the contents of the stream if it is active or fails silently
if it has ended.

In order for `experimental_resume` to work as intended, it requires the
usage of the
[`resumable-stream`](https://www.npmjs.com/package/resumable-stream)
package for stream creation and a redis instance for the package to
manage the pub/sub mechanism.

## Verification

An example has been added at `examples/next-openai/app/use-chat-resume`
to test the feature. Follow the following steps to test it end-to-end:
1. Run the development server
2. Navigate to `http://localhost:3000/use-chat-resume`
3. Send a message that will have a longer generation duration, example
"Write an essay about Michael Jordan"
4. Once the generation starts, click the chat id above to open the
conversation in a new tab
5. Verify the stream gets resumed

## Tasks

- [x] Tests have been added / updated (for bug fixes / features)
- [x] Documentation has been added / updated (for bug fixes / features)
- [x] A _patch_ changeset for relevant packages has been added
- [x] Formatting issues have been fixed (run `pnpm prettier-fix` in the
project root)

…el#6133)

## Background

Before in issues like vercel#5499 &
vercel#5833, if users ran into an
issue where the messages array failed to parse correctly they'd run into
a difficult to debug error `Invalid prompt: messages must be an array of
CoreMessage or UIMessage`

## Summary

This PR extends these error messages to include more details on what
exactly went wrong, which is useful information for debugging when stuff
breaks.

On security: I think this is an okay change since the data sent is not
private

…errors.

Without this, with maxSteps set, we sometimes see messages sent to the API like this:

```
{
  role: 'assistant',
  content: [ { text: '\n\n' }, { toolUse: [Object] } ]
},
```

This leads to API errors like this:

```
The text field in the ContentBlock object at messages.$n.content.0 is blank. Add text to the text field, and try again.
```

This change simply filters out this useless but apparently harmful message.
