Describe the bug
I followed the amplify gen2 doc to add REST api to the backend, then I wrote a simple test suite to test if resources were provisioned correctly. This is the test suite:
But when I first ran the test, I got an issue SyntaxError: Unexpected token 'export', and screenshot is below:
So, I went to jest.config.ts and re-wrote the next/jest config like this:
module.exports = async () => ({
...(await createJestConfig(customConfig)()),
transformIgnorePatterns: ['node_modules/?!(@aws-amplify/backend)'],
});
. Then I ran the test again, this time it gave me a different issue:
I am not sure what does this
No context value present for amplify-backend-namespace key really mean, but my goal was to run some quick tests to make sure the underlying resources are provisioned correctly so that I don't have to do it by writing some scripts using aws cli or aws sdk after the whole backend environment is setup and running, instead I could focus on e2e tests or something else.
Expected behavior
The tests should be running successfully.
Reproduction steps
- clone the example repo:
git clone https://github.com/MyNameIsTakenOMG/amplify-next-backend-testing.git
- install the dependencies:
npm i
- run the test:
npm run test
- Please note: I did not configure the nextjs frontend to connect with the amplify backend, instead I simply just took advantage of nextjs auto-configuration of jest so that I could run some tests for the backend resources.

Hello, @MyNameIsTakenOMG 👋. This looks to be specific to Jest rather than a bug with the Amplify library, but want to see if we can get you unblocked! There's been similar issues that reported getting this error with some potential workarounds in issue aws-amplify/amplify-js#11435 (here and here) where there were updates made to the transformIgnorePatters to add modules to resolve. Can you let me know if anything along those lines helps resolve the issue for you?
Hi @cwomack , thank you for your prompt response, sir! And yes, I agree with you that this issue may be more jest-related rather than amplify-related, and also took a look at the links you shared with me. Well, I did the same thing as other guys, I mean the transformIgnorePatters thing. The moment I saw the error SyntaxError: Unexpected token 'export', I changed the configuration for transformIgnorePatters as I mentioned above in the bug description section. And then it led me to the issue that we talk about here, haha.
Anyways, instead of keeping getting stuck with this issue, I wrote a script using aws cli to test out my resources in the real amplify backend environment, even though it is a bit time-consuming. That said, I will keep looking at this issue, and update if I found something.
And again, thank you for the help, sir!
@MyNameIsTakenOMG, we'll transfer this over to the amplify-backend repo after reviewing it further internally and update this to a feature request to expose the namespace key.
I'm also running into this while testing with Vitest. Hopefully there'll be some guidance on this.
