Unknown application error occurred

リンクされている issue 再現用リポジトリから始め、yarn を実行し、説明されているとおりに api/login/checksecurityans を実行してください。api/login/checksecurityans.js から api/services/jwt-token-service.js、jsonwebtoken/sign.js までスタックを追跡します。報告された PEM エラーが jsonwebtoken で再現可能なのか、それとも再現環境に固有なのかを特定できれば完了です。

Description

I have been working with Vercel support to resolve an issue where the jsonwebtoken package is encountering an error, "Unknown application error occurred". Vercel has directed me to open an issue here.

Reproduction

https://github.com/vercel-support/issue-reproduction

Here are my steps.

1. Clone the repo https://github.com/vercel-support/issue-reproduction
2. run, "yarn"
3. run the code in the api/login/checksecurityans file
4. Open Postman and POST to localhost:3000/api/login/checksecurityans
5. Get this error if you ran the code using 'vercel dev'

Or if you ran the file using node you might see an error like this one

Unknown application error occurred

I do have a package.json file and it does include jsonwebtoken.

Environment

"jsonwebtoken": "8.5.1"
