Angular2-jwt: The inspected token doesn't appear to be a JWT

[guillaume-skwid]

Hi

Using angular-jwt with Angular 5 I'm getting Error: The inspected token doesn't appear to be a JWT when trying checking the token expiration with isTokenExpired('refresh_token')

The token is valid according to jwt.io

I got the same error in my interceptor while doing
this.jwtHelper.isTokenExpired('access_token')

By simply having this.jwtHelper.isTokenExpired() in my interceptor it works (though I'm not sure of the behavior ....) but in the case of the refresh I absolutely need to check the refresh token (otherwise it'd be non-sense).

I can't seem to find a solution to this :)

Not sure if you're not already doing this but are you getting the token before checking it ?

like

const refreshToken = tokenGetter();
this.jwtHelper.isTokenExpired(refreshToken)

@maikdiepenbroek I had the same issue as OP, and that was the cause. Good catch, thank you.
