Deno fetch type error: client from Deno.createHttpClient() not recognized by TypeScript / VSCode

[Lqm1]

Question
When I call fetch(url, { client }) with a client created by Deno.createHttpClient(), VSCode / TypeScript reports a type error even though the runtime supports this option. @types/node is not explicitly installed but is present transitively (e.g. via nodemailer). How do I make the editor recognize Deno's client type?

Reproduction steps

1. Create a Deno script using Deno.createHttpClient() and fetch(url, { client }).
2. Open the project in VSCode (no explicit @types/node install).
3. Observe a TypeScript error on the fetch call.

Environment

• Deno runtime (version 2.5.1)
• VSCode with TypeScript language features (may or may not have Deno extension)
• Some @types/* present transitively (e.g. nodemailer)

Can you share your compilerOptions? You might have to replace some instance of deno.ns with deno.window in your compilerOptions.lib. Also please share a screenshot of the error so we can confirm it's coming from Deno.
