ERR_OSSL_BAD_DECRYPT in Vercel Function with Snowflake Secure Embedding

Hello Vercel Community,

I need help diagnosing a Snowflake Streamlit secure-embedding integration in my Vercel portfolio project.

The Vercel Function Logs show a POST 500 error from /api/embed-url with:

ERR_OSSL_BAD_DECRYPT

The error occurs in Node.js crypto.createPrivateKey() before the Snowflake authentication request completes.

Vercel's Agent clarified that the text displayed in the environment-variable input fields is placeholder text, not my actual stored credentials.

A local OpenSSL check also showed that the public key derived from my private-key file does not match my original public-key file. The original public-key fingerprint was registered with my Snowflake user, so I have not yet confirmed that the private and registered public keys form a matching pair.

Could someone advise on the safest way to diagnose this issue in a Vercel Node.js Function?

I am using the Vercel Hobby plan and would appreciate community guidance.

I will not share private keys, passphrases, JWTs, or other credentials.
