Describe the bug

https://nextjs.org/docs/app/building-your-application/deploying/static-exports#version-history

v14.0.0 | next export has been removed in favor of "output": "export"

I changed next.config.js for the above changes and pushed codes and the build failed.

Error: The "target" property is no longer supported in next.config.js.

I got the above error even though I set output without setting target. I assume this is due to the amplify adapter setting target.

Expected behavior

No error.

Reproduction steps

1. Install next.js 14.
2. update next.config.js  "output": "export".
3. (maybe not needed) Change build config in web console. Amazon Linux 2023 / Node.js 18 / Next.js latest
4. build fail.

Code Snippet

const nextConfig = {
  output: 'export',
};

module.exports = nextConfig;

Hi @matamatanot thank you for opening this issue. I’m transferring it over to the Hosting repository for better assistance.

[saulonunesdev]

updating the build image worked for me. https://github.com/aws-amplify/amplify-hosting/issues/3295#issuecomment-1843645331

I changed AWS Linux 2023 and got an error that /usr/bin/aws: No such file or directory. Any idea where it was changed?

./update_amplify_redirections.sh

cat $OUTPUT_FILE /usr/local/bin/aws amplify update-app --app-id $AWS_APP_ID --custom-rules file://redirections.json

[WARNING]: ./update_amplify_redirections.sh: line 97: /usr/bin/aws: No such file or directory [ERROR]: !!! Build failed [ERROR]: !!! Error: Command failed with exit code 127

Edited: simply aws removing /usr/bin/. Success!

Even if you use AWS Linux 2023, the build will fail. Even if the platform value is set to "Web", "platform": "WEB_DYNAMIC" is automatically set.

Error: The "target" property is no longer supported in next.config.js.
