Steps to Reproduce

Package that @sentry/aws-serverless used

PS C:\repos\serverless-backend> npm ls require-in-the-middle

    └── [email protected]

Expected Result

Fix the package issue for @opentelemetry/instrumentation

Actual Result

Using deprecated function and show warnings in AWS Lambda

[s1gr1d]

Hello, can you run npm explain (docs) to see which package is responsible for installing punycode? This issue probably has to be fixed by the package using punycode as they mention that it has to be imported in a special way.

Cross-Linking this as the issue has been already posted in require-in-the-middle: nodejs/require-in-the-middle#95

[betimer]

@s1gr1d it shows in eslint, but the final bundle I am using esbuild and eslint is not included in the final bundle. The final bundle if I run npm ls require-in-the-middle, it only shows @sentry/aws-serverless is using it.

I would assume that require-in-the-middle is not actually the culprit here, but showing up because it is wrapping modules under the hood, maybe 🤔 Your logs also show that punycode actually comes from eslint, so I'd look into updating this to get rid of this! It does not appear as if this is related to us, we do not ship any code that depends on punycode as far as I can tell.

[s1gr1d]

From what I see after a quick search in the eslint repository, it's an issue that's already opened multiple times there (https://github.com/eslint/eslint/issues?q=is%3Aissue%20deprecation%20punycode%20).

Apparently Node 22.14.0 stopped emitting this warning: eslint/eslint#19375 (comment)

[mydea]

Closing this as it does not seem to be originating from our code.
