When building flows with conditional logic in WhatsApp Flow Builder, it’s easy to overlook the condition field in the If component. But even a minor mistake, like leaving it blank or inserting just a space, triggers this error:

**INVALID\_PROPERTY\_VALUE**

**Expected property 'condition' to contain at least one operand.**

This error means Flow Builder was expecting a valid expression to evaluate (like a boolean check), but got nothing instead.

## Quick Fix

Always provide a valid boolean expression in the **"condition"** field of an If component. An empty string, space, or null will break the flow. Replace

```
"condition": " "
```

with something meaningful like:

```
"condition": "${data.isUserActive}"
```

## Why This Happens

The If component expects a "condition" field that resolves to true or false. An empty string (" ") is not a valid boolean expression, so the engine has nothing to evaluate.

### Common Causes:

- A copied placeholder left unchanged

- Using **" "** instead of **"${someCondition}"**

- Forgetting to bind data using **${}**


## How to Fix It

Update your condition with a valid expression or boolean flag from your data object. For example:

```
{
  "type": "If",
  "condition": "${data.hasAccess}",
  "then": [
    {
      "type": "Text",
      "text": "You have access"
    }
  ],
  "else": [
    {
      "type": "Text",
      "text": "Access denied"
    }
  ]
}
```

## Best Practice

Always ensure your condition is:

- Not empty

- A valid expression

- Properly referencing existing data
