## Constructors
### TraconException\(\)
Creates a new error.
```csharp
public TraconException()
```
### TraconException\(string\)
Creates a new error.
```csharp
public TraconException(string message)
```
#### Parameters
`message` [string](https://learn.microsoft.com/dotnet/api/system.string)
The error message.
### TraconException\(string, Exception?\)
Creates a new error.
```csharp
public TraconException(string message, Exception? innerException)
```
#### Parameters
`message` [string](https://learn.microsoft.com/dotnet/api/system.string)
The error message.
`innerException` [Exception](https://learn.microsoft.com/dotnet/api/system.exception)?
The underlying error, or [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null) when there is none to carry.
## Properties
### ErrorType
Gets the stable error type name written to the run record.
```csharp
public virtual string ErrorType { get; }
```
#### Property Value
[string](https://learn.microsoft.com/dotnet/api/system.string)
#### Remarks
Defaults to the full name of the exception type, so today's behaviour does
not change. A derived type overrides this member when the record has to be
machine readable โ for example [TraconContentFilteredException](/api/tracon.traconcontentfilteredexception/)
writes `content_filtered`. Reports and alert rules can rely on this
stable name instead of an assembly name.
The value is written to `RunError.Type` and **carries no secret**.
