after creating a new feature with one rule it now returns:

array is gone and instead I see

variations

is this intentional? has I missed something in setting up this feature/rule?

what are the end points for the two payloads?

we are running our own version(not cloud)

I could give you the whole json output or our url and DM a secret if that would help

what it looks like that for old features I get rules as https://docs.growthbook.io/api#tag/FeatureExperimentRule_model and for new ones as https://docs.growthbook.io/api#tag/FeatureExperimentRefRule_model may be you'd know why?

Hi Victor, we did change how experiment rules work in version 2.5. Previously, the rule type was ​`experiment`​ and everything was defined inline - traffic weights, conditions, trackingKey, etc.. Starting in 2.5, new experiment rules added to features use the new rule type ​`experiment-ref`​ instead. With this new rule type, there is a foreign key to an Experiment object (experimentId). All of the targeting and rollout info is defined on the Experiment instead. There's a separate API endpoint for fetching experiments.
