Designer error loading project

I get the following error trying to load one of my projects in the designer.

com.inductiveautomation.ignition.client.gateway_interface.GatewayException: Gateway Error 500: Unable to read response from Gateway. at com.inductiveautomation.ignition.client.gateway_interface.GatewayInterface.newGatewayException( at com.inductiveautomation.ignition.client.gateway_interface.GatewayInterface.getResponse( at com.inductiveautomation.ignition.client.gateway_interface.GatewayInterface.sendMessage( at com.inductiveautomation.ignition.client.gateway_interface.GatewayInterface.sendMessage( at com.inductiveautomation.ignition.designer.gateway.DTGatewayInterface.loadProject( at com.inductiveautomation.ignition.designer.IgnitionDesigner$ at com.inductiveautomation.ignition.client.util.gui.ProgressDialog$ at Source) Caused by: org.xml.sax.SAXParseException: The end-tag for element type "Response" must end with a '>' delimiter. at Source) at$JAXPSAXParser.parse(Unknown Source) at com.inductiveautomation.ignition.client.gateway_interface.GatewayInterface.getResponse( ... 6 more Ignition v7.0.1 (b4461) Java: Sun Microsystems Inc. 1.6.0_11

After a gateway restart this went away. ??

This kind of error is caused by the Gateway failing when trying to stream a response to the Designer - the Designer ends up getting half a response and can’t figure out what it means.

There is almost assuredly a corresponding error message in your Gateway’s wrapper.log from the same time that should shed some more light on the issue.
