"ERROR!" when attempting to initiate Field Test Data Processor

I’m attempting to utilize the Field Test Data Processor. I had installed and configured Extension and was in the process of debugging my setup. Now, when I attempt to Launch the extension I receive a page with the simple “ERROR!” message. Screenshot attached. No other message is presented. I have uninstalled, rebooted and reinstalled the extension. Any help is appreciated. Thanks!

Firmware version: WisGateOS_2.3.1_RAK
Extension version: 1.2.0

Hello @joedonn ,

Did you update the firmware version after installing the extension?
Which version did you update from (what was the previous firmware version before you updated it to the current one)?

Regards,
