Do you have a simple flow for me to test? are the variables used in custom tool or other places? chatflow or agentflow

ExportData.json

docker run -it --rm --name flowise -p 3000:3000 flowiseai/flowise

# Import data
# Go config, enable override value

curl http://localhost:3000/api/v1/prediction/479d9db3-9606-40e6-b78c-bd4405a87931 \
     -X POST \
     -d '{"question": "Hey, how are you?", "overrideConfig": {"vars":{"test":"overrided"}}}' \
     -H "Content-Type: application/json"

In console log, it shows the vars still original value.
