Research direction
Start by reproducing the scrape failure with the TiFlash exporter and Prometheus v3.0.1. Inspect the exporter's scrape response, especially its blank Content-Type, and compare it with Prometheus's fallback_scrape_protocol requirement. Done means the target scrapes successfully without the reported non-compliance error.
