Hi,
i had the probleme in my project.
I did this on my jest.config.js file :

transformIgnorePatterns: ['node_modules/(?!@angular|@stomp/rx-stomp)'],

don't if it will work for you.

Hi,
this issue still exists and the recommended solution did not work for us. Is there any update comming on that topic?

thanks

I do not use Jest. If anyone is able to create a simple project that shows the problem using GitHub, I can fork and try to fix the issue.

I have the same Problem. Has someone a solution for this jest Error? @yuchuan1 and @nspourriel did you find a solution for this?

for me the following works in an angular project:

const esModules = [
  '@angular/animations',
  '@angular/cdk',
  '@angular/cdk',
  '@angular/common',
  '@angular/compiler',
  '@angular/core',
  '@angular/forms',
  '@angular/localize',
  '@angular/material',
  '@angular/platform-browser-dynamic',
  '@angular/platform-browser',
  '@angular/router',
  '@angular/service-worker',
  '@ng-bootstrap/ng-bootstrap',
  '@fortawesome/angular-fontawesome',
  '@stomp/rx-stomp',
  '@stomp/stompjs',
  'dayjs/esm',
].join('|');

module.exports = {
  transformIgnorePatterns: [`/node_modules/(?!${esModules})`],
  transform: {
    '^.+\\.(ts|js|mjs|html|svg)$': [
      'jest-preset-angular',
      {
        tsconfig: '<rootDir>/tsconfig.spec.json',
        stringifyContentPathRegex: '\\.html$',
        isolatedModules: true,
        diagnostics: {
          ignoreCodes: [151001],
        },
      },
    ],
  },
  //...
};

no, it doesn't work with @krusche 's suggestion.
I am still stuck with 1.14
