ava has no default export.

Please provide details about:

• What you're trying to do

Based on a recent blog post of Sindresorhus I'm trying to convert my most low level npm package to node 12.
I changed the package.json to

"type": "module",
"exports": "./dist/index.js",
"engines": { "node": ">=12.13" },

• What happened

Ever since this I cannot execute Ava tests. I get this error:

test/ava.ts(1,8): error TS1192: Module '"/Users/lucaban/ghq/github.com/mesqueeb/is-what/test/ava"' has no default export.

• What you expected to happen

No error.

Here is my repo:

https://github.com/mesqueeb/is-what/tree/esm

See the esm branch ↑

Also, this is the Ava config:

"ava": {
    "extensions": [
      "ts"
    ],
    "require": [
      "tsconfig-paths/register",
      "ts-node/register"
    ]
  },

I know there are so many recourses about ESM, but it's come to a point where everyone is saying different things and I can't seem to figure out exactly what I'm doing wrong.

If someone can point me into the correct direction, that would be great!
