Troubleshooting
Common problems and how to solve them
2 min read
If you get stuck while working, check the items below.
I don't see any data on screen
- Check that the component is bound to data.
- For a List, check that array data is bound to the List and that the components inside the cell are bound to each field.
- Check that the data actually contains values. (If the values are empty, the screen will look empty too.)
Nothing happens when I press the button
- Check that an Action Flow is connected to the button via an event (usually Touch).
- Check that the Action Flow contains an action to run.
The API response isn't showing up on screen
- Check that the API Call action is connected to the event that runs it (e.g., Page Appear).
- Check that the response schema matches the actual response structure. You can use Send Test Request to receive the real response and auto-generate the schema.
- Check that the binding tokens in the request URL and headers are substituted with the correct values.
Navigation isn't working
- Check that the Page Navigation action has a target Page specified to navigate to.
Most behavior problems can be checked and fixed right away in Preview. Build in small steps and run often.
