## Error Message

`AUR0155: Expression error: unexpected end of expression: "{{expression}}"`

## Description

This error occurs when the parser reaches the end of the expression while still expecting more tokens (for example a missing closing bracket/quote/parenthesis).

## Example Trigger

```html
<!-- ❌ Missing closing quotes/brackets -->
<div textcontent.bind="user['name"></div>
<div textcontent.bind="(count + 1"></div>
<div textcontent.bind="items[0"></div>
```

## Solution

* Close quotes, brackets, and parentheses.

## Troubleshooting

* Look for unmatched `'`, `"`, `]`, `)` in the expression.
* If the expression is complex, move it to a view-model getter/method.
