## Error Message

`AUR0168: Expression error: unexpected character: "{{expression}}"`

## Description

This error occurs when the parser encounters a character that is not valid (or not supported) in the current position in the expression.

## Example Trigger

```html
<!-- ❌ '@' is not valid here -->
<div textcontent.bind="@user"></div>
```

## Solution

* Remove/replace the unexpected character and use valid expression syntax.

```html
<!-- ✅ -->
<div textcontent.bind="user"></div>
```

## Troubleshooting

* Look for accidental characters introduced by copy/paste.
* If the expression comes from a generated template, inspect the generated output.
