TypeScript ` .d.ts` declaration file not found

Question

I am trying to write TypeScript typings for a JavaScript module in a TypeScript subproject. My project structure looks like this

In the file server/index.ts, I wrote:

import { handler } from '../build/handler.js'

In server/tsconfig.json, I wrote

"include": [
    "./*.ts"
],

I have to store the .d.ts file outside the build folder because the build folder is overwritten with each build. According to Could not find a declaration file for module 'module-name'. '/path/to/module-name.js' implicitly has an 'any' type, I wrote a file server/global.d.ts with contents

declare module "handler" {
    export function handler(arg: any): any;
}

Running npx tsc --project server/tsconfig.json I get the error:

Could not find a declaration file for module '../build/handler.js'. '/absolute_path/build/handler.js' implicitly has an 'any' type.",

It seems like the global.d.ts file is not picked up. How should I name the global.d.ts file and what should the contents be?

I did change the module name to a relative path, but that gives an error about ambient modules.

Furthermore, I have tried changing the name according to answer to Typescript: .d.ts file not recognized. But it doesn't work.

(I would rather not use // @ts-ignore.)
