Error receiving message from Frida exported function in Pyro proxy

Hi Brida Team ( cc: @federicodotta ), I'm running to an issue when trying to get the result from calling exported Frida function. Brida exported function is working fine and return a string value, but something went wrong with the Pyro proxy so I cannot get the result from that ( I"m calling exported function from Custom Burp Plugin )

The code and stack traces are below: Java code calling Frida exported function:

String pyroUrl = "PYRO:BridaServicePyro@localhost:9999";
                try {
                    PyroProxy pp = new PyroProxy(new PyroURI(pyroUrl));
                    String ret = (String)pp.call("callexportfunction","encryptdecryptaes");
                    stdout.println("Result from Frida JS: " + ret);
                    pp.close();
                } catch (Exception e) {
                    // EXCEPTION HANDLING
                    stderr.println("Error from PyroProxy: " + e.getMessage());
                    StackTraceElement[] exceptionElements = e.getStackTrace();
                    for (int i=0; i< exceptionElements.length; i++) {
                        stderr.println(exceptionElements[i].toString());
                    }

Error from Burp plugin extension:
