Hi Growthbook Team! How do I get the rule that is used from

onFeatureUsage

callback? For example, I have 3 rules as below, the first two are force rules, and the last one is for A/B experiments. I have tried several times but it seems

ruleId

is not working...

What SDK are you using?

Hi @fresh-football-47124, I used

@growthbook/growthbook-react

sparse-guitar-91772

The version is

0.13.0

I wonder if the method isn’t calling

evalFeature

what method are you calling?

oh, prob not: “The

result

argument is the same thing returned from

gb.evalFeature

.”

Yes, I use

onFeatureUsage

and want to do some statistics on our own Kibana platform.

I read it from your official documentation

sparse-guitar-91772

03/16/2023, 8:15 AM

However, the

ruleId

is empty no matter how...

Can you grab the feature payload JSON?

sparse-guitar-91772

03/16/2023, 8:31 AM

Do you mean the response for

<https://cdn.growthbook.io/api/features/SDK-id>

API request?

sparse-guitar-91772

03/16/2023, 8:34 AM

I got this ⬇️

sparse-guitar-91772

03/16/2023, 8:36 AM

Seems like I don't have

id

field for each rule object, do you know how to set it?

fresh-football-47124

03/16/2023, 8:47 AM

ya, I see that - let me open a ticket with the team on this

fresh-football-47124

03/16/2023, 8:47 AM

the SDK has it as optional

fresh-football-47124

03/16/2023, 8:49 AM

are you using the legacy SDK or the new one?

Hi @fresh-football-47124 I also found another bug

sparse-guitar-91772

03/16/2023, 8:50 AM

I think it should be the latest one, will check later

sparse-guitar-91772

Issue: the

source

value is incorrect Reproduce Steps: 1. Set some force rules 2. Use them in the code, the experiment result will fall into one of the force rules. 3. Check the

result

data from

onFeatureUsage

callback Expected Results:

result.source = '_force_'

Actual Results:

result.source = 'experiment'

I found this issue thanks to GrowthBook Chrome Extension:

sparse-guitar-91772

03/16/2023, 8:56 AM

@fresh-football-47124 Yes, the latest one

fresh-football-47124

03/16/2023, 8:57 AM

I’ll follow up when I have a chance to sync with the team

That last one doesn’t sound right - but let me make a test case

fresh-football-47124

I think I can reproduce that

I’ll share my example code with the team, perhaps I’m just not understanding ‘force’ there - perhaps we mean it to mean a rule as been applied

Yes, can refer to this doc: https://docs.growthbook.io/lib/js#evalfeature
