I am also facing the same issue in my Vue2 app. It works with version 8.5.1 but not with 9.0.0.
milinddhamu commentedon Feb 9, 2024
this issue is mentioned here , as after update they added some additional parameter to sign an 'ordinary' or 'illegal' string.

I hope this works well for guys and maybe can close this thread.

In my Vue2 application I only use the jwt.verify method. The proposed fix does not work for me. My tokens are signed in the backend with version 9
milinddhamu commentedon Feb 15, 2024
As per code example you are using an string 'fooSecret' which may not be correct as per v9 they added some strict rules for generating token so when we use older method it's breaking. Please if you got any lead help me out also about how this works as they demands more of proper values and their types as per docs.

I don't see any answer to the problem in the documentation.
In the backend my token is signed with version 9 of jsonwebtoken in the following way:
jwt.sign(payload, this.privateKey, {expiresIn: '1h'})In Vue2 frontend the token is decoded with version 8.5 of jsonwebtoken in the following way:
jwt.verify(token, publicKey)And it works.
But if I upgrade to version 9 I get the error invalid 'instanceof' operand KeyObject
milinddhamu commentedon Feb 16, 2024
So issue is when you're verifying, is it generating token perfectly. If you sign any illegal key in v9 it'll show same error. As i used it in next.js not tried in vue.

As I have understood jsonwebtoken package is not designed for browsers and you should use packages that designed for client-side as such jwt.io javaScript libraries

That's what I did. I opted for jwt-decode and jwt-encode
