Hello,

We have created tags using scripting function.
However, when we try to export tags to json, we are getting below error. We are not able to identify the issue. Could you please review and let me know what is wrong?

java.io.IOException: com.inductiveautomation.ignition.client.gateway_interface.GatewayException: java.lang.RuntimeException: Error cloning object through serialization.
