Error Message Structure (MANDATORY)
Every DAQS error message must follow this fixed structure.
#### Issue
#### Solution
#### Explanation
Two types of placeholders exist:
| Placeholder | Braces | Source |
|---|---|---|
{{name}}, {{parameterName}}, {{assemblyCode}}, ... |
Double {{ }} |
Fields from the filter output object |
{ActualValue}, {ExpectedValue} |
Single { } |
Injected by DAQS at render time |
{ActualValue} and {ExpectedValue} are special — DAQS fills them in automatically based on the validator result. All other fields come from the filter output and require double curly braces.
Error Message Template
#### Issue
The element **{{name}}** contains an invalid value for parameter **{{parameterName}}**.
The current value is **{ActualValue}**, but this value is not allowed.
---
#### Solution
Open the element in Revit and update the parameter **{{parameterName}}** so that it contains a valid value according to the project standard.
---
#### Explanation
Correct parameter values are required to maintain reliable BIM data.
Incorrect values can affect scheduling, classification, quantity take-offs, and downstream analysis.
