Hey everyone! Has anyone had issues with feature flag values not being the same when accessed in a Flutter environment vs. a NodeJS environment? The feature is being assigned based on the
userId
property and both the front and back-end are assigning the attribute to the same value.

Hi Connor - did you set the hashing version?
to version 1?

Let me check!
How exactly do I check that?

are you launching the experiment via the feature flag?

Ahhh I see we are using V2

Gotcha, it was in the fine print! I see Flutter does not support V2

No worries! I have to destroy and recreate the feature flag to change the hashing version correct?
So after looking around for a little bit, I can't seem to figure out how to set the hashing version when creating an experiment. Is this not possible at the moment?

it is possible
but I believe we hide it on initial creation, and expose it on editing
but I know that part of the product is changing a lot

You are correct sir. Thank you we found it.
I will test right now to see if that solves our issue!
There unfortunately still seems to be a mismatch even when reverting back to V1 hashing. Any other ideas as to what the cause could be?

can you make sure the SDK payload for the NodeJS SDK says v1?

Never mind! We had to create a new experiement entirely to get it functioning properly. Even after updating to have it use V1, there was a mismatch. Luckily we caught this early though and creating a new experiment was no issue for us.
Thank you for the quick help!
