Thanks for opening up the issue!

I spun up a new project but was not able to reproduce this.

Do you have a repo I can look at?
If not, do you have an example of the function and test that you are running?

Thank you again!

I got this error message as well, when upgrading my project. I was importing firebase-functions-test from a jest setup file and getting the same error as @dima11221122. After upgrading my jest/ts-jest/ts-node dependencies to the latest versions this error went away.

@ericallam Oh man, I totally forgot about that!!

If you're using jest < 28, you'll run into this issue.

Please try upgrading to jest@28 and let me know if you can still reproduce this.

More info:

• Support package exports in jest-resolve jestjs/jest#9771 - original issue
• feat: support exports in package.json jestjs/jest#11961 - Fix
• https://github.com/facebook/jest/milestone/14?closed=1 - jest@28 milestone
• Jest testing failing with new import entry points firebase-admin-node#1465 - Similar Issue

I'll open a pr to include jest@28 as a peer dep to reduce this problem. Thank you for raising this!
