Unable to create instance of JwtClaimsBuilder in Quarkus application - jwt

Question

I am currently working on the Quarkus application.
I have created an authentication service which will validate user and will create JWT token and send it to the client after successful authentications.
But currently, I am facing issue while creating a JWT token. For token creation, I am using
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-smallrye-jwt</artifactId>
</dependency>
Please refer below code for which is used for token creation.
public static String generateTokenString(PrivateKey privateKey, String kid,
String jsonResName, Map<String, Long> timeClaims) throws Exception {
JwtClaimsBuilder claims = Jwt.claims(jsonResName);
long currentTimeInSecs = currentTimeInSecs();
long exp = timeClaims != null && timeClaims.containsKey(Claims.exp.name())
? timeClaims.get(Claims.exp.name()) : currentTimeInSecs + 300;
claims.issuedAt(currentTimeInSecs);
claims.claim(Claims.auth_time.name(), currentTimeInSecs);
claims.expiresAt(exp);
return claims.jws().signatureKeyId(kid).sign(privateKey);
}
Once the above method is executed then JwtClaimsBuilder claims = Jwt.claims(jsonResName);
throws NullPointerException as it is unable to parse JWT Claims.
Please refer to below logs

This is a bug in quarkus dev mode. Will be fixed in 1.5.0. See also here: https://github.com/quarkusio/quarkus/issues/9135
