Debug blank screens by opening Chrome DevTools, checking the console for errors and stack traces, inspecting the DOM to verify elements are rendered, and reviewing network activity for failed requests. Start by reproducing the issue consistently, then capture logs to identify whether the problem is a runtime error, failed API call, or layout issue.

Inspect layout issues using DevTools Elements tab to examine DOM structure and computed styles, check the console for measurement or sizing errors, and use the Network tab to confirm all resources loaded. Minimal fixes with clear logging help isolate whether the problem stems from CSS, missing data, or runtime calculation errors.

Open Chrome DevTools console to capture error output and stack traces, use the Network tab to inspect failed requests and response data, and examine the Elements tab to verify DOM state. Reproduce the issue, collect all signals, then apply targeted fixes based on what the logs reveal.

Yes, Chrome DevTools Network tab shows all requests, responses, and failures for WebF apps. Inspect request headers, response bodies, and timing to identify why requests fail, then cross-reference errors with console output and DOM state to pinpoint the root cause and apply fixes.

Apply minimal, reversible fixes after collecting console logs, network data, and DOM inspection through DevTools. Document your changes clearly, test each fix individually, and refer to MCP documentation for known issues and recommended debugging practices before deploying changes.

Familiarity with Chrome DevTools basics—console, Network, and Elements tabs—and JavaScript stack traces helps, but the core workflow is straightforward: reproduce, open DevTools, collect signals, and apply targeted fixes. MCP documentation provides known issues and recommended debugging procedures.
