Error Message

AUR0160: Expression error: expected identifier to come after binding behavior operator: {{expression}}

Description

This error occurs when a binding behavior operator (&) is used without providing a behavior name.

Example Trigger

<!-- ❌ Missing behavior name -->
<input value.bind="firstName &">

Solution

Provide a binding behavior name after &.

<!-- ✅ -->
<input value.bind="firstName & debounce:200">

Troubleshooting

• Check for trailing & in expressions.

• Ensure the binding behavior is registered (otherwise you may get an evaluation error instead).
