Stryker does not detect any of the tests in angular application

Question

im trying to do mutation testing for my application, however when i run my stryker mutator it does not take any of the tests into the analysis and performs a dry run.

WARN InputFileResolver Glob pattern "src/**/*.ts" did not result in any files.
(10452) WARN InputFileResolver Glob pattern "!src/**/*.spec.ts" did not exclude any files.
(10452) WARN InputFileResolver Glob pattern "!src/test.ts" did not exclude any files.
(10452) WARN InputFileResolver Glob pattern "!src/environments/*.ts" did not exclude any files.
(10452) WARN InputFileResolver No files marked to be mutated, Stryker will perform a dry-run without actually mutating anything. You can configure the `mutate` property in your config file (or use `--mutate` via command line)

As you can see i have declared my glob patterns correctly but here is the complete stryker config:

/**
 * @type {import('@stryker-mutator/api/core').StrykerOptions}
 */
module.exports = {
  _comment:
    "This config was generated using 'stryker init'. Please see the guide for more information: https://stryker-mutator.io/docs/stryker-js/guides/angular",
  mutate: [

    "!=src/**/*.spec.ts",
    "!src/test.ts",
    "!src/environments/*.ts",
  ],

This is my configuration file which does pick up my tests. I am using the latest version.

/**
 * @type {import('@stryker-mutator/api/core').StrykerOptions}
 */
module.exports = {
    coverageAnalysis: 'off',
    packageManager: 'npm',
    reporters: ['html', 'clear-text', 'progress'],
    htmlReporter: {
        baseDir: 'docs/mutation'
    },
    testRunner: 'jest',
    mutate: [
        'src/**/*.ts',
        'src/**/*.service.ts',
        '!src/**/*.interface.ts',
        '!src/**/*.fake.ts',
        '!src/**/*.mock.ts',
        '!src/**/*.spec.ts',
        '!src/**/__mocks__/*',
        '!src/main.ts'
    ],
    timeoutMS: 30000   // Use extended timeoutMs for test run to remove Time Out Results
};
