## Error Message

`AUR0154: Expression error: invalid member expression: "{{expression}}"`

## Description

This error occurs when a member access (dot/bracket access) is malformed or uses a syntax that Aurelia’s expression parser does not support.

## Example Trigger

```html
<!-- ❌ Malformed member access -->
<div textcontent.bind="user.[name]"></div>
<div textcontent.bind="user."></div>
```

## Solution

* Use valid JavaScript-like member access:

```html
<!-- ✅ -->
<div textcontent.bind="user.name"></div>
<div textcontent.bind="user['name']"></div>
```

## Troubleshooting

* Check for accidental punctuation around dot/bracket access.
* Ensure bracket access is properly quoted or uses a valid expression inside `[]`.
