This function was removed from the Gateway entirely as it is potentially harmful. It is only present in Gateway versions 7.9.0 - 7.9.3. It is not present in any prior or later versions of Ignition. This function is replaced by system.util.sendRequest() , which is much more secure and was introduced in 7.9.3. If you are using this function, it is highly recommended that you upgrade to at least 7.9.3 and use system.util.sendRequest() instead.
