# Troubleshooting

Resolve an empty drawer, rejected connections, and missing flow captures.

## The drawer is empty

Confirm `enabled: true` on the server and `enabled={true}` on the component in development. Make a request through the client returned by [`inspector.createClient()`](/api/reference/#adapter-createclient). Creating a second ordinary SDK client bypasses recording.

Then check that inference routes and inspector endpoints use the same instance and process. On Next.js, use a stable [`getJevDevtools()`](/api/reference/#getjevdevtools) key and restart after changing configuration. Requests in another worker or serverless instance are not aggregated.

## The endpoint returns 403

Compare the configured origin with the browser URL, including scheme, hostname, and port. Check that proxies preserve the path and Host. A cross-origin browser endpoint is unsupported.

Node middleware rejects non-loopback peers without [`authorize`](/api/reference/#createjevdevtools). Shared or tunneled environments need application authorization. A custom session must resolve consistently for inference and inspection.

## The endpoint returns 404

Disabled adapters intentionally hide their endpoints. In development, confirm the middleware runs before your application's fallback. In Next.js, use `[[...path]]`, not `[...path]`, so the base route exists too. Align custom endpoints in both the server and React component.

## A flow runs but is not recorded

Pass `devtools: inspector` to [`run()`](/api/reference/#flow-run) and use the instrumented client. Keep the flow and adapter on Node. A definition describes a graph; it does not execute until [`run()`](/api/reference/#flow-run) is called.

## Configuration changes are ignored

The first options factory passed to [`getJevDevtools()`](/api/reference/#getjevdevtools) wins for that key. Restart the process after changing origin, redaction, session, or authorization options. Dispose only for shutdown or deliberate reinitialization, not after every request.

## Data looks incomplete

Captures are bounded and can be redacted or truncated. Known credentials cannot be recovered from the inspection copy. The unreleased display-masking prop can reveal supported personal fields only if those fields were retained by the server. Use the Questions picker or Raw view for large collections; browser Find does not cover unmounted virtualized cards.
