Absolute imports get treated as externals

[PolyphonyRequiem]

I've got a relatively fresh project. Under src I have:

│   index.ts
│   TabletopSimulatorService.ts
│
└───domain
        TabletopSimulatorServiceMessages.ts

when I run npx tsdx build I get the following output:

│   index.d.ts
│   index.js
│   TabletopSimulatorService.d.ts
│   ttstk-channels.cjs.development.js
│   ttstk-channels.cjs.development.js.map
│   ttstk-channels.cjs.production.min.js
│   ttstk-channels.cjs.production.min.js.map
│   ttstk-channels.esm.js
│   ttstk-channels.esm.js.map
│
├───domain
        TabletopSimulatorServiceMessages.d.ts```

I would expect to see a .js and .js.map for both TabletopSimulatorService and domain/TabletopSimulatorServiceMessages

I'm assuming I need to change something in my configuration, but cannot find sufficient documentation.

Figured it out promptly after this, literally a day after first encountering it.

Change from

import * as tts from 'TabletopSimulatorService';

to
import * as tts from './TabletopSimulatorService';
