If you're working with WhatsApp Flow JSON and see an error like this:

**INVALID\_DEPENDENCIES**

**Footer should have property left-caption when property right-caption is present.**

—or the reverse:

**Footer should have property right-caption when property left-caption is present.**

It means your component is missing a required companion property. Let’s walk through what’s happening and how to fix it.

## What This Error Means

This error shows up when a property depends on another one being present, but it’s not.

In this case, the Footer component expects that if you define either left-caption or right-caption, you must define both. They’re a pair.

## The Problem

Here’s a Flow JSON example that will trigger the error:

```
{
  "screens": [
    {
      "id": "FIRST_SCREEN",
      "layout": {
        "children": [
          {
            "type": "Footer",
            "left-caption": "left",
            "on-click-action": {
              "name": "complete",
              "payload": {}
            }
          }
        ]
      }
    }
  ]
}
```

### What’s wrong here?

- left-caption is defined.

- right-caption is missing.

- WhatsApp expects both if either one is used.


## The Fix

To fix this, add the missing right-caption field, like so:

```
{
  "screens": [
    {
      "id": "FIRST_SCREEN",
      "layout": {
        "children": [
          {
            "type": "Footer",
            "left-caption": "left",
            "right-caption": "right",
            "on-click-action": {
              "name": "complete",
              "payload": {}
            }
          }
        ]
      }
    }
  ]
}

```

Now, the dependency is satisfied. No more error.
