Thank you for the clarification. I can confirm that this was indeed the issue (we removed old rules after migration by running the removal script). I applied your suggested workaround by adding an old style rule, and after that I was able to successfully delete the gateway group.

Thanks again for the guidance!

Hello,
I'm currently running OPNsense version 26.1.2. When I attempt to remove a gateway group, I receive the following error:

Code Select Expand

PHP Fatal error: Uncaught TypeError: Cannot access offset of type string on string in /usr/local/www/system_gateway_groups.php:41
This error prevents the gateway group from being removed. The gateway group was created by mistake, as I only have one gateway. I can reproduce this issue by creating a second gateway group, adding my gateway to it, and then attempting to remove the group. The same error occurs, and the gateway is not removed.

I have two OPNsense routers, and I was able to replicate this issue on both of them.

Let me know if you need any additional information.
