VS Code: "Not prefixed with... and not in import map from ..."

[saeho]

Version: Deno 1.14.3

Hello,

I have a VS code issue where import-map configured NPM packages are showing as errors. I saw a few threads like this but none of the threads I read solved my problem (even though the issues were very similar.

Here's an example:

On the Server Deno repo
This will show as an error in VS Code ("not prefixed with / and not in import map from..."):

import { ApolloServer } from '@apollo/server';

This is my deno.json:

"imports": {
    "@apollo/server": "npm:@apollo/server@^4.10.4",
    "graphql": "npm:graphql@^16.8.1"
  }

However, this exact imports map works in my Fresh Deno app repo and VS Code does not complain.

Is the deno.json at the root of your repo? Do you have a repo I can take a look at?

[saeho]

Yes, deno.json is at the root, and deno.json file works properly as it should. All the imports does the job properly, it's just VS Code that fails.

You can take a look at the repo but it's private. Can I give you private access?

[lucacasonato]

Sure, can you invite @nayeemrmn and @nathanwhit?

If you're using deno.enablePaths ensure it contains the deno.json.

Also, try running deno upgrade.
