Hi I am self hosting GrowthBook v4.3.0 and on publishing i am greeted with the following error: Cannot read properties of undefined (reading 'type')

hi Neil

yep I can connect, everything else works

oh

I have a has a few more problems but i have fixed that by adding indexes. just stuck on this one.

can you share or DM a screen shot? Anything in the name or rules which might be unescaped?

Fixed it, i created a duplicate of the feature which worked and noticed something weird in the json document. This section:

"production" : {
            "rules" : [ ],
            "enabled" : false
        },
        "upgradetest" : {
            "enabled" : true
        }
    }

Removed this bit

Deleted         "upgradetest" : {
            "enabled" : true
        }
