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.
  • 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.
