Spring Base64 problem when I Override "configureMessageConverters"

Affects: 5.3.13

---

I'm using fusionauth-jwt, when I override configureMessageConverters like this:

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {

        ObjectMapper mapper = new ObjectMapper();

        mapper.registerModule(new Hibernate5Module());
        mapper.registerModule(new JavaTimeModule());

        mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);

        converters.add(new MappingJackson2HttpMessageConverter(mapper));

    }

The fusionauth-jwt verifier throws this exception:

io.fusionauth.jwt.InvalidJWTException: The encoded JWT is not properly Base64 encoded.

I report the problem to fusionauth-jwt, but they say this is not from their side. Then I tried another JWT library called java-jwt, but the problem persist and it says:

The input is not a valid base64 encoded string.

I found the problem, the token was enclosed in double quote. Sorry to bother
