Jest Test Suite Failed after adding the firebase-admin-CodePudding

I added a firebase-admin in the NestJS Project, the unit test pass in the local code but fails in the CI/CD Pipeline.

Test suite failed to run
    Jest encountered an unexpected token
    This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.
    By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".
    Here's what you can do:
     • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
     • If you need a custom transformation specify a "transform" option in your config.
     • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.
    You'll find more details and examples of these config options in the docs:
    https://jestjs.io/docs/en/configuration.html

All the tests passed locally from VS Code

I tried adding the testPathIgnorePatterns and other settings provided on the web. Didn't work.

CodePudding user response：

The Nullish Coalescing Operator (??) was introduced to Node in version 14. Update your CI/CD pipeline to be a newer version of Node. The current version is 18 and I believe 12 is no longer LTS so upgrading is definitely something to look into.
