Using functions inside a typescript class - “TypeError: is not a function”

[neilgibert1234]

'm trying to setup comlink in a typescript project but can't work out why this doesn't work.

My calling method/ class

import Mehs from "@/myTest.worker";

export default class TestCalling{``

public async callMyTestMethod(): Promise {
const meh: Mehs = new Mehs();``
const ss: string = await meh.greet("Neil");
console.log(ss);
}
}`
My test class/method

export default class TestWorker{
public async greet(subject: string): Promise {
return new Promise((resolve) => {
resolve(Hello, ${subject}!);
});
}
}
This give me the following error : "TypeError: meh.greet is not a function"

However if i just export a function it works i.e.

export async function greet(subject: string): Promise {
return new Promise((resolve) => {
resolve(Hello, ${subject}!);
});
}
But i want to use a class as it may have multiple functions that i want to call. What am i doing wrong ?
