function is not defined when using async function using babel and Typescript in development

[wbusby88]

Hi,

I'm using Babel and Typescript in development, which I compile to JS for production. However, when trying to use microjob with an async function working locally I get a _functionName is not defined error. Here is some simple code to reproduce:

//index.ts
import express from "express";
import {job, start} from "microjob";

const app = express();

app.get("/", async function(req: express.Request, res: express.Response) {
    await start();

    const test = async () => {
        return 'test';
    }

    // all the below fail with the async before the function name above
    // const result = await job(test);
    // const result = await job(() => {
    //     return test();
    // }, { ctx: { test }});
    const result = await job(async () => {
        return test();
    }, { ctx: { test }});
    // const result = await job(async () => {
    //     const response = await test();
    //     return response;
    // }, { ctx: { test }});

    res.send(result);
});

const port = 4790;
app.listen(port);
console.log(`view app at http://localhost:${port}`);

My package.json:

.babelrc

  ]
}

My tsconfig.json

  },
  "include": [
    "index.ts"
  ]
}

Node version 12.6.2

To note: Using an async function passed

Thanks for any help in advance :+1:

Try to change your target parameter to "ES2020" in the tsconfig.json.
