@ziluvatar reply please

The payload of that token is not well built, if you try to base64 decode you'll find that it does not contain a JSON payload, you will see something like

{"sub":"1234567890","name":"���H�X]�MLML

@ziluvatar yes , I know, I just told that throwing SyntaxError is not good behavior, instead we must throw JsonWebTokenError

Do you have other idea?

[ziluvatar]

I tagged this and another similar one as bug. I mean, you are right we should raise one of our errors.

@ziluvatar The issue a about stale , Do you have plan to fix it? and the issue tagged as a bug

I've changed a single line returning default error to JsonWebTokenError type , see if this solves the problem #735
