That looks like you’re trying to execute a long-running job via a http request. The Cloudflare Proxy has a 100 second response timeout. Unless you are on Enterprise, you can’t change that. Your options are essentially:
1: Have that job run in the background and return instantly, could poll it for updates/job status
2. Disable proxy on that hostname/lose Cloudflare’s HTTP benefits/protections
3. Call it another way (ex. via CLI, or locally on the web server bypassing Cloudflare)
