The inspected token doesn't appear to be a JWT

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 😃

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

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)
