TypeError: First parameter has member 'readable' that is not a ReadableStream.

First of all, thanks for your work on this module. It's great to not having to wrap the API manually in my project. I'ved noticed that it works great, returns data, but throws this error when it's being used inside a Nuxt 3 Server:

Do you have any idea what this could cause? If you think this is specific to Nuxt, I'll create an issue there.

Checking the stack trace this seems like more an issue with undici & subsequently node-fetch-native. Having a quick look through the undici repo issues there's nothing mentioning First parameter has member 'readable' that is not a ReadableStream so I'm not too sure right now.

I will take a deeper look into this issue at a later date.

Nice job, you API key is now public and its working

@Parth971 That's why I wrote "Never do that in your code!" lol. It's just a test project.

Suddenly running into this issue now as well. Didn't change code around creating the checkout URL.

Any update or more insights in the meantime?

EDIT: Found the issue, which seems to have been a peer dependency conflict. It started happening after I installed the openai npm module. This was the error I got:

When I commented out the import of the openai module, the error did not occur. The openai module has web-streams-polyfill as a dependency:

"openai": {
      "version": "4.12.3",
      "resolved": "https://registry.npmjs.org/openai/-/openai-4.12.3.tgz",
      "integrity": "sha512-Kw8M8qioKg+iw2tCpdJ1G772uV0tk4SRF1MtySYSPr82YH+Csl61kYv2KzKAOqINcOVn5eSN26t0ImIsdJexfw==",
      "requires": {
        "@types/node": "^18.11.18",
        "@types/node-fetch": "^2.6.4",
        "abort-controller": "^3.0.0",
        "agentkeepalive": "^4.2.1",
        "digest-fetch": "^1.3.0",
        "form-data-encoder": "1.7.2",
        "formdata-node": "^4.3.2",
        "node-fetch": "^2.6.7",
        "web-streams-polyfill": "^3.2.1"
      },
      "dependencies": {
     //...
      }
    },

Lemonsqueezy.ts only has undici as a dependency:

"node_modules/lemonsqueezy.ts": {
      "version": "0.1.7",
      "resolved": "https://registry.npmjs.org/lemonsqueezy.ts/-/lemonsqueezy.ts-0.1.7.tgz",
      "integrity": "sha512-7COfsFaPVsz4ik6+b5hVI/PMyu6FE+PmrbNvk1G89P826XVRRnidVhDAes+Ed42RLyigc8bBHFbuUZSglPTO0g==",
      "dependencies": {
        "undici": "^5.20.0"
      },
      "engines": {
        "node": ">=16.*"
      }
    },

It seems that undici is using web-streams-polyfill under the hood, from the error stack trace..

What fixed the error in my case was the order of importing. When I changed it so openai is imported after lemonsqueey.ts, the error did not occur anymore.
