javalangIllegalStateException Method syncAccountInfo not annotated with HTTP method type ex GET POST

This exception is thrown when a method named "syncAccountInfo" is not properly annotated with an HTTP method type. In Java, annotations are used to provide additional information to the compiler or runtime environment. In this case, the annotation that is missing is the HTTP method type, which specifies the type of request that the method can handle (e.g. GET, POST, PUT, DELETE).

To fix this error, you need to add the appropriate HTTP method type annotation to the method. For example, if the method should handle a GET request, you should add the "@GET" annotation before the method definition:

@GET
public void syncAccountInfo() {
  // method implementation
}

If the method should handle a POST request, you should use the "@POST" annotation instead:

@POST
public void syncAccountInfo() {
  // method implementation
}

Make sure you use the correct annotation for the type of request that the method should handle
