Why `structuredOutputs` fail to valid since this morning? #4062

Hello,
First, thanks for the lib.

I'm using AI SDK with OpenAI to generate structuredOutputs. Until this morning, it was working just fine.

  // Generate a JSON object and return it
  const { object } = await generateObject({
    model: openai('gpt-4o-mini-2024-07-18', { structuredOutputs: true }),
    messages: context.conversation,
    schema: Augmented_Query, // See `_schema.ts`
    temperature: 0.5
  })

However, this morning, I've updated AI SDK to latest version and I've got (sometimes) a validation schema whereas I didn't change anything. And, indeed, value does not include location key. Hence the error.

Trying another time, the schema error was different because value returns an array where a string was asked...

Did you see the same problem?
Is it linked to AI SDK Core (I think not because I've tried to downgrade to previous version) or OpenAI (I didn't change model though).

Thanks.
