Do not use default exports in your code:

// somefile.ts
export default function (...) {

// somefile.ts
export function whatevar(...) {

import { whatevar } from './somefile';

AOT is incompatible with default exports (among other things). But unlike other incompatibilities, this one generates the most cryptic error message ever.
