Angular2: Unable to locate the 'environment' namespace

After configuring my tsconfig.json, I can now use short import paths in my code for brevity. This allows me to do things like

import { FooService } from 'core'
instead of the longer
import { FooService } from '../../../core/services/foo/foo.service'
.

Everything was working fine until I created a new file and encountered an error with one of the imports:

Cannot find namespace 'environment'.

The error is triggered by this line:

import { environment } from 'environment';

It's puzzling because all my other services have the same import without any issues, the error only pops up in this newly created file.

Here is a snippet of my tsconfig.json:

{
  "compileOnSave": false,
  "compilerOptions": {
    "outDir": "./dist/out-tsc",
    "baseUrl": "src",
    "paths": {
      "core": ["app/core"],
      "core/*": ["app/core/*"],

      "shared": ["app/shared"],
      "shared/*": ["app/shared/*"],

      "modal": ["app/modal"],
      "modal/*": ["app/modal/*"],

      "environment": ["environment/environment"] // The problematic line
    },
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es5",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2016",
      "dom"
    ]
  }
}

The paths seem correctly set up, so it's perplexing why only this file is throwing an error. Can anyone shed light on how to resolve this issue?

ISSUE RESOLVED

After troubleshooting, I discovered a small error in my code that was causing the issue. It was quite challenging to pinpoint as the intellisense feature did not flag it.

The mistake was here: url: environment.serverUrl;

What it should have been:

url: string = environment.serverUrl;

It turns out I mistakenly used a value instead of defining the correct type. Silly oversight on my part!
