Error Message

AUR0153: Expression error: expected identifier: "{{expression}}"

Description

This error occurs when the parser expects an identifier (a variable/property name) but finds something else.

Example Trigger

<!-- ❌ Missing identifier after dot -->
<div textcontent.bind="user..name"></div>

<!-- ❌ Missing identifier after '|' (value converter) -->
<div textcontent.bind="message |"></div>

Solution

• Ensure property access uses a valid identifier (obj.prop).

• Ensure value converters / behaviors specify a name (value | converter, value & behavior).

Troubleshooting

• Look at the expression shown in the error and find where an identifier is missing.

• Simplify the expression until it parses, then re-introduce parts.
