Has anyone tried proxying requests from Promptfoo through a local Burpsuite proxy? I'd like to see the requests and responses resulting from red teaming an application that uses an AI Agent to talk to an LLM. I'm following the instructions here https://www.promptfoo.dev/docs/faq/#how-do-i-use-a-proxy-with-promptfoo. I've added the following to an .env file in the directory I'm running

promptfoo redteam

from:

# Promptfoo Proxy with authentication
export HTTPS_PROXY=127.0.0.1:8080
# SSL certificates - Absolute path
export PROMPTFOO_CA_CERT_PATH=/Users/user/burpsuitecacert.der

When running

promptfoo -v redteam run

I get the following output in verbose mode:

[apiHealth.js:17] [CheckRemoteHealth] Checking API health: {"url":"https://www.promptfoo.app/health","env":{"httpsProxy":"127.0.0.1:8080"}}
[apiHealth.js:36] [CheckRemoteHealth] Making fetch request: {"url":"https://www.promptfoo.app/health","options":{"headers":{"Content-Type":"application/json"}},"timeout":5000,"nodeVersion":"v24.7.0"}
[fetch.js:114] Using custom CA certificate from /Users/user/burpsuitecacert.der
[fetch.js:122] Using proxy: https://127.0.0.1:8080/
[apiHealth.js:95] [CheckRemoteHealth] API health check failed: {"error":"Request timed out after 5000 ms","url":"https://www.promptfoo.app/health"}

When I do not use the proxy, it works as it should. When I proxy local browser traffic to the API endpoint I want to test, it works as it should. I definitely have access to https://www.promptfoo.app/health so it seems the problem is with the communication between Promptfoo and Burpsuite proxy. Any ideas where to look when troubleshooting this will be very welcome!
