Chart Widgets behind load balancer throw RootTagMissingFromViewException

I have a few standard bar chart widgets on the default dashboard. They all load successfully in a single-server environment. When I put my application behind a load balancer (multiple server instances, no sticky sessions), multiple livewire/update requests fail with:
Livewire encountered a missing root tag when trying to render a component. When rendering a Blade view, make sure it contains a root HTML tag.
Livewire encountered a missing root tag when trying to render a component. When rendering a Blade view, make sure it contains a root HTML tag.
If I turn on sticky sessions in my load balancer or reduce the number of server instances to 1, the problem goes away. I also do not receive the error in my single container development environment. I've tested deploying with/without php artisan optimize and/or php artisan filament:optimize It seems like any request that goes through the load balancer and is handled by an instance other than the one that handled the initial page load is failing. Appreciate any ideas/assistance!

What is your cache mode. I think if you are on file, you must have sticky sessions to work livewire. It apparently will work with Redis\Memcache without sticky sessions.

Thanks @Matthew , we have both SESSION_DRIVER and CACHE_DRIVER set to redis and confirmed that they are working as expected
