Hi Arpan - I assume this with the react SDK implementation?

It looks like in the GrowthBookProvider, you accidentally passed in a string instead of the growthbook object

08/05/2022, 10:12 PMthanks. trying again
I am confused by serve table in growthbook. Not sure when should I turn it ON or OFF? Also when Name is used. I don’t see name included in API response

those two cases in your experiment rule have two different values (on and off) it's up to you to see whatever values you want - if you set them to the same, you'll be running an A/A test
The experiment key, I assume you mean, is used in the trackingCallback - you should see it in your console log

08/05/2022, 10:18 PMso for a/b test which should I leave one on and another off?

it doesn't matter really - but typically 0'th index is the control (so off)

08/05/2022, 10:19 PMok and by name I mean next column values which is default and fivision in pic I shared. I don’t see those in api response
what are they used for?

oh, thats for growthbook users
sometimes 'on' and 'off' are hard to parse - so you can use that name for something more understandable - like 'showing new version of x'

08/05/2022, 10:32 PMyou mean api response? wouldn’t it be same as previous as we have just changed it in devtools but not actually changed it?

oh
I've sometimes had some problems with the devtools - you can make sure the SDK is working correctly by adjusting the id: "123" to something else to rebucket you, and see if you get the other variations
the devtools is just for debugging

08/08/2022, 3:00 PMoh marketing team can’t use that dev tools to swap different variations at will?
