Solution:

I downgraded bcryptjs to version ^2.4.3, and the issue was resolved:

npm install [email protected]

Now, password hashing works without errors.

Question:

• Why does bcryptjs v3.0.0 require WebCryptoAPI or an external crypto module, while v2.4.3 works fine?
• Is there a proper way to make it work with v3.0.0 without downgrading?

Hope this helps others facing the same issue!
