ts-jest: ts-jest 25.3 breaks VSCode debug run

Issue :

Having to revert to ts-jest 25.2.1 because I receive this error when running tests for a specific file, despite blowing away node_modules:

Could not find source file: '/Users/pete.burkindine/git/ccxp/ccxp-client/node_modules/@ngrx/store/bundles/store.umd.js'.

The file is there and a normal run of ng test does not have the same issue.

Here is the command that was run (by VS code launch setup on a specific file):

cd /Users/pete.burkindine/git/ccxp/ccxp-client ; /Users/pete.burkindine/.nvm/versions/node/v12.13.1/bin/node --inspect-brk=3326 node_modules/.bin/jest libs/features/provider-compare/src/lib/components/provider-data/provider-data-row-header-set/provider-data-row-header-set.component.spec.ts --config /Users/pete.burkindine/git/ccxp/ccxp-client/.debug/jest.config.js --runInBand --runTestsByPath --detectOpenHandles

Here is the jest.config used by the debugger

module.exports = {
  rootDir: '../',
  globals: {
    'ts-jest': {
      stringifyContentPathRegex: '\\.html?$',
      tsConfig: '<rootDir>/.debug/tsconfig.spec.json',
      astTransformers: [
        'jest-preset-angular/build/InlineFilesTransformer',
        'jest-preset-angular/build/StripStylesTransformer'
      ]
    }
  },
