(bug) [relay-proxy] Override configuration via env variables in `retrievers` does not work about go-feature-flag HOT 5 CLOSED

Hi @thomaspoignant , I try to fix it, but I've found a bug in local, when I set yaml in the local:

listen: 1031
pollingInterval: 1000
startWithRetrieverError: false
retriever:
  kind: http
  url: https://raw.githubusercontent.com/thomaspoignant/go-feature-flag/main/examples/retriever_file/flags.goff.yaml
retrievers:
   - kind: file
     path: examples/retriever_file/flags.goff.yaml
  - kind: file
    path: examples/retriever_file/flags.goff.yaml

exporter:
  kind: log
enableSwagger: true
authorizedKeys:
  evaluation:
    - apikey1 # owner: userID1
    - apikey2 # owner: userID2
  admin:
    - apikey3

the retrievers of config can't load from the yaml file.

from go-feature-flag.

@luanxuechao from your example I see an indentation issue in your file on the providers.
Can you try this one instead?

listen: 1031
pollingInterval: 1000
startWithRetrieverError: false
retriever:
  kind: http
  url: https://raw.githubusercontent.com/thomaspoignant/go-feature-flag/main/examples/retriever_file/flags.goff.yaml
retrievers:
  - kind: file
    path: examples/retriever_file/flags.goff.yaml
  - kind: file
    path: examples/retriever_file/flags.goff.yaml

exporter:
  kind: log
enableSwagger: true
authorizedKeys:
  evaluation:
    - apikey1 # owner: userID1
    - apikey2 # owner: userID2
  admin:
    - apikey3

Can you double check if this will solve your issue?

Hi @thomaspoignant, it doesn't work. I run the relayproxy/main.go with goff-proxy.yaml, and debug it. I'm new developer of golang. I also can reproduce it with json config. go version is: go version go1.22.3 darwin/arm64

from go-feature-flag.

@luanxuechao I've tried the same file as you and I don't reproduce.
What I have done:

1. copy/paste the file (the one edited by myself in the previous comment) in the root directory of go-feature-flag.
2. Start the relay-proxy in IntelliJ (inside cmd/relay-proxy/main.go).
3. Add a debugger point at this line:

   go-feature-flag/cmd/relayproxy/main.go

   Line 96 in c982515

   apiServer := api.New(proxyConf, services, zapLog)

4. Here is the output I got:
