When working with conditional rendering in JSON-based UI frameworks one of the most frustrating errors to debug is:

**INVALID\_PROPERTY\_VALUE: Property ‘condition’ should have valid expression syntax.**

## Quick Fix

Make sure the condition inside your If component is a valid boolean expression. The expression must include:

- Proper opening and closing parentheses

- Valid operands (e.g., ${data.value\_1})

- Valid operators (e.g., ==, !=, &&, \|\|)

- Correct string formatting (with closing quotes if applicable)


## What Causes This?

The error arises from broken or malformed logic inside the condition field of an If component. In the example below:

```
"condition": "))${data.value_1}(("
```

The syntax is totally invalid. There are extra parentheses, and the value is not part of any logical expression.

### Common Triggers for INVALID\_PROPERTY\_VALUE

1\. Missing parentheses

```
"condition": "${data.age > 18"  // Missing closing parenthesis
```

2\. Unquoted strings

```
"condition": "${data.city} == Delhi"  // Delhi should be quoted
```

3\. Wrong operator usage

```
"condition": "${data.status} || ${data.mode}"  // No boolean context
```

4\. Type mismatch

```
​"condition": "${data.age} == 'eighteen'"  // Integer vs string​

```

5\. Broken interpolation

```
"condition": "${data.value_1  && }"  // Missing second operand
```

## Best Practice for Writing Conditions

A valid example might look like this:

```
"condition": "${data.value_1} == 'active' || ${data.count} > 5"
```

You can also wrap your logic in extra parentheses for clarity:

```
"condition": "(${data.value_1} == 'active') || (${data.count} > 5)"
```
