Hello, we have an MQTT engine 5.0.1 on an ignition gateway 8.3. We are using source control and after switching branches where the MQTT config doesn’t change, we are having an issue where the gateway webpage stops displaying the settings in the config file, all the checkboxes and entry fields go blank. In addition, when we go to select an option and save it this error pops up.
This is causing an issue for us where the gateway starts to block node and device commands even tho in the config its set to false.
We are able to fix this manually sometimes if we delete the entire mqtt config folder(com.cirruslink.mqtt.engine.gateway) and allow it to regenerate and then we overwrite it with our old mqtt config folder with our settings and do a filescan. This method is mostly repeatable but sometimes we need to do it multiple times. The webpage will start working again after this and we can unblock the node/device commands.
Any advice here on how to prevent this issue would be appreciated! thank you
