Hello Everyone! I'm new to Growthbook and exploring the product for our new project. I have setup growthbook proxy and now trying to connect it with cloud instance, it manages to pull the initial value of feature flag and save it in-memory but subsequent polling calls fail with below error :

are you using the cdn url?

@fresh-football-47124 This is the command I'm using to run it on mac

docker run --platform linux/amd64 -d -p 3300:3300 \
  -e "GROWTHBOOK_API_HOST=<https://cdn.growthbook.io>" \
  -e "SECRET_API_KEY=my-secret-value" \
  --name gbproxy growthbook/proxy

okay

Are you running this locally or deployed

I'm running it locally on apple M1 Node version is 18.18.2

Ah. It won’t work then. Growthbook Cloud needs to send info to the proxy via webhooks. You configure that in your SDK Connection. But GB can’t post to a local proxy on your dev box

Thank you @happy-autumn-40938 . This makes sense, in-memory cache busting must be done via this webhook. I'll move my growthbook proxy setup to server. Extended question - Is there a way to evaluate Remote Execution feature as a non-premium user? PS: We are in POC phase

you'd probably want to sign up for a free pro trial for Remove Evaluation. You can do this through the Growthbook app. Nothing additional needed on the proxy setup for enrolling in the trial
