Client - propagateHeaders is depending on the JWT token to be in the header. about light-4j HOT 2 CLOSED

Several people report this issue and this is not a bug. The propagateHeaders method will pass the traceabilityId(if exist), correlationId and subject JWT token to the request to the next service. In additional, it will call OAuth2 server to get access JWT token and pass it as well. The exception happens when OAuth2 server is not available. Since there is no dependency between client and security module so client doesn't know if security is enabled or not. To make it work, the API handler should check if security is enabled before calling this method.

Here is the code in the beginning of the handler.

    static Map<String, Object> securityConfig = (Map)Config.getInstance().getJsonMapConfig(JwtHelper.SECURITY_CONFIG);
    static boolean securityEnabled = (Boolean)securityConfig.get(JwtHelper.ENABLE_VERIFY_JWT);

And later on you can call the method wrapped by if.

            if(securityEnabled) {
                Client.getInstance().propagateHeaders(httpGet, exchange);
            }

The example ms_chain has been updated with this approach. The issue is closed.
