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

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

Solution

• Use valid JavaScript-like member access:

<!-- ✅ -->
<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 [].
