ERROR: [plugin: deno] Unhandled media type Json.

I’m using a deno library that imports a JSON file with:

import countries from "https://cdn.jsdelivr.net/gh/umpirsky/country-list@2.0.6/data/en_US/country.json" assert { type: "json" };

This is happening in the code for an island, what I get in the console is:

Loading module from “http://localhost:8000/_frsh/js/63eb35c3-6547-4f71-9fc2-b111894c1374/island-playground.js” was blocked because of a disallowed MIME type (“text/html”)

And going to the URL in this error gives me:

An error occured during route handling or page rendering.

So my question is, are JSON imports not allowed in islands? And if they’re allowed - what am I doing wrong? The library should work as expected, at least it does when I run the test suites.

Thanks

This is fixed in Fresh 1.0.2.

That is likely a different bug - you are probably importing JSON in the form of import { foo } from "./data.json" assert { type: "json" } instead of import data from “./data.json” assert { type: “json” }`. JSON imports only allow importing the entire value as a default import.
