-## Publishing
+## Troubleshooting
 
-### Version Update
+### API Connection Issues
 
-Bump the version in `package.json` before publishing. Use `npm version` to update the version and create a git tag:
+-   **CORS errors** — Ensure the Flowise server allows requests from your app's origin. Check the Flowise CORS configuration.
+-   **401 Unauthorized** — Use an API Key (Settings > API Keys), not a JWT user token. Verify the key is passed via the `token` prop.
+-   **Wrong `apiBaseUrl`** — The URL must point to the Flowise API root (e.g., `http://localhost:3000`), not a subpath.
 
-```bash
-# Prerelease (for testing)
-npm version prerelease --preid=dev   # 0.0.0-dev.1 → 0.0.0-dev.2
+### Validation Errors
 
-# Patch / Minor / Major (for stable releases)
-npm version patch                    # 0.0.1
-npm version minor                    # 0.1.0
-npm version major                    # 1.0.0
-```
+-   **"Flow is empty"** — Add at least one node to the canvas.
+-   **"Missing start node"** — Every flow requires a `startAgentflow` node. Add one from the palette.
+-   **"Disconnected nodes"** — All non-sticky-note nodes must be reachable from the start node. Connect any orphaned nodes.
+-   **"Cycle detected"** — Flows must be acyclic (DAGs). Remove the edge that creates the cycle.
 
-### Verify Before Publishing
+### Theme Issues
 
-```bash
-# Build and check the tarball contents
-pnpm build
-npm pack --dry-run
-
-# Full publish dry-run (runs prepublishOnly + simulates upload)
-npm publish --dry-run
-```
+-   **Dark mode not applying** — Pass `isDarkMode={true}` as a prop. The component uses its own design tokens and does not inherit from the host app's theme.
+-   **Style conflicts** — Ensure `@flowiseai/agentflow/flowise.css` is imported. The component's CSS variables are scoped to avoid collisions.
 
-### Publish
+### Variables Not Resolving
 
-```bash
-# Prerelease — tagged so `npm install @flowiseai/agentflow` won't pick it up
-npm publish --tag dev
+-   **Variable not in picker** — Variables are sourced from upstream nodes. Ensure the source node is connected and upstream of the current node.
+-   **Incorrect path** — Variable syntax is `{{nodeName.outputKey}}`. Check that the node name and output key match exactly.
 
-# Stable release — gets the `latest` tag
-npm publish
-```
+### Async Options Not Loading
 
-> The `prepublishOnly` script automatically runs `clean` and `build` before every publish, so stale dist files are never uploaded.
+-   **Empty dropdowns for models/tools/credentials** — These load from the Flowise API. Verify `apiBaseUrl` and `token` are correct and the server is running.
+-   **Network errors in console** — Check browser DevTools for failed requests. The API client logs errors to the console.
