Try:

import { createEnv } from "@t3-oss/env-nextjs/dist";
import { createEnv } from "@t3-oss/env-core/dist";

Thank you for the reproduction repo @ryota-murakami - so much easier to help then :)

This line is the issue: https://github.com/ryota-murakami/guestbook/blob/main/tsconfig.json#L13. Update that to use Bundler module resolution which supports reading package.json#exports conditions.

For some good and modern tsconfig presets:

• Matt's tsconfig recommendation: https://www.totaltypescript.com/tsconfig-cheat-sheet
• create-next-app has also started using a more modern tsconfig lately: https://github.com/vercel/next.js/blob/canary/packages/create-next-app/templates/app/ts/tsconfig.json
• and ofc create-t3-app https://github.com/t3-oss/create-t3-app/blob/main/cli/template/base/tsconfig.json

Downgrading to v0.9.1 fixes the issue.

Thank you all! I will provide a reproducible next time :)

related issue: #168

[juliusmarminge]

Needs reproduction repo. Likely a tsconfig option you have that doesnt support esm packages.

0.9 was a breaking change and we now only support esm + modern module resolutions (Node16+)

[deadcoder0904]

using "moduleResolution": "Bundler" in tsconfig.json does fix the red-squiggly lines in vscode.

[juliusmarminge]

Considering this closed then, also added a note in docs about esm only. Reopen if you still have issues

[ryota-murakami]

@juliusmarminge Thank you for sharing great links, that works!

I just stumbled across this issue too.

Maybe its worth adding a line into the README about this, so people can self-serve easier in future?

so whats the final resolution now? downgrading to 0.91?

no, swap moduleResolution: node to moduleResolution: bundler in your tsconfig (or NodeNext if transpiling using tsc).

still face the same issue for expressjs
