Research direction
Start by reproducing the malformed token case with jwt.verify using the issue's example, then trace how verify reaches decode and how jws.decode errors are propagated. Done means malformed input consistently produces JsonWebTokenError rather than a generic Error, with the behavior covered by the relevant existing tests.

Description
Description
Sometimes decode, and in turn - verify, will throw Error instead of JsonWebTokenError. That makes it hard to distinguish errors in the calling code.
Reproduction
var jwt = require("jsonwebtoken")
const malformed_token='notbase64atall';
jwt.verify(
malformed_token,
'Secret',
{
algorithms: [ 'HS256' ],
}
);
