# Boolean or Array Data Not Showing

**Symptom:**\
Some response fields are missing from the Outputs list.

**Reason:**\
Adalo only supports **Text**, **Number**, and **Date/Time** fields for Custom Action Outputs. Boolean (`true` / `false`) values and nested arrays are not supported.

**Solution:**\
Convert Boolean values to text or numbers in your API (for example, `"true"` instead of `true`). For nested arrays, use Make or another tool to flatten the data before sending it back to Adalo.
