Link to the code that reproduces this issue

To Reproduce

Using NextJS 14

• npm run build (success)
• launch the app (fails - Request reference error)

Current vs. Expected behavior

I am using AWS Amplify to host my NextJS app; using a custom build image: public.ecr.aws/docker/library/node:20.9.0. Everything works fine with NextJS 13.5.6 but when upgrading to NextJS 14 I encounter an error.

When running npm run build, the app compiles successfully but when navigating to the app using my browser it does not work. The AWS amplify logs show this error :

class NextRequest extends Request { 
ReferenceError: Request is not defined

Locally on my computer (with node 20.0.9 as well) it works perfectly, either npm run build or running in development mode (npm run dev). I tried using the default build image provided by AWS but the latest node version is 18.13: lower than the version required by NextJS 14.

I found this issue : https://github.com/vercel/next.js/issues/57214; I am guessing the problem comes from the node version, but I do not know how to solve it as you can see below running node -v outputs v20.9.0.

For now I downgraded to NextJS 13.5.6 and everything works fine.

Here is the build output - everything build successfully :

But when opening the app (using its domain) there is an error, the site does not appear in Chrome or Safari and in the AWS logs I get the reference error shown just above.

Verify canary release

• I verified that the issue exists in the latest Next.js canary release

Provide environment information

I am using AWS Amplify to host my NextJS app; using a custom build image: public.ecr.aws/docker/library/node:20.9.0

NextJS 14
Node 20.9.0

Which area(s) are affected? (Select all that apply)

Not sure

Additional context

I tested using the latest canary version, the same error occurs. I guess the problem comes from AWS Amplify and not NextJS but I am completely stuck and tried everything I could with my fairly limited skills as I am still learning how all of this works.

I’d be happy to add more information if needed, thanks a lot in advance !

Here are my AWS build specification (amplify.yml):
