Error generating images with workers-ai-provider

[notreux]

I'm getting an error when using workers-ai-provider, even though the same request works fine when made manually with axios using the same API key and account ID

Environment

• Runtime: Bun 1.2.21
• OS: Windows 11 Pro (23H2)

Example:

const { image } = await generateImage({
	model: workersai.image('@cf/black-forest-labs/flux-1-schnell'),
	prompt: 'A futuristic cityscape at sunset',
});

Error:

13419 |   } else if (stream2 && typeof stream2.arrayBuffer === "function") {
13423 |   } else {
13424 |     throw new Error("Unsupported stream type: expected a Web ReadableStream or an async iterable stream");
                  ^

can you make a small repro repo?

My bad, the error I shared in my previous post was incorrect, I was trying to debug the error myself and accidentally shared the error from my modified version instead of the clean one. Sorry about that. That’s why the code fragment I sent didn’t match what’s in workers-ai-provider.

Here’s the correct error:

13376 |   if (value === "" || !value) return void 0;
13377 |   const number4 = Number(value);
13378 |   return Number.isInteger(number4) ? number4 : void 0;
13379 | }
13380 | async function streamToUint8Array(stream2) {
13381 |   const reader = stream2.getReader();
                         ^
TypeError: null is not an object (evaluating 'stream2.getReader')
