## Constructors

### <a id="Tracon_TraconAgentSourceException__ctor_System_String_System_String_System_String_System_Exception_"></a> TraconAgentSourceException\(string, string, string, Exception?\)

Creates a normalized agent-source exception.

```csharp
public TraconAgentSourceException(string sourceName, string errorType, string message, Exception? innerException = null)
```

#### Parameters

`sourceName` [string](https://learn.microsoft.com/dotnet/api/system.string)

The stable name of the source that failed.

`errorType` [string](https://learn.microsoft.com/dotnet/api/system.string)

The stable error type code.

`message` [string](https://learn.microsoft.com/dotnet/api/system.string)

The normalized error message.

`innerException` [Exception](https://learn.microsoft.com/dotnet/api/system.exception)?

The raw underlying error, or [null](https://learn.microsoft.com/dotnet/csharp/language-reference/keywords/null) for a contract violation the
catalog itself detected, which has no underlying exception to carry.

## Fields

### <a id="Tracon_TraconAgentSourceException_SourceContractErrorType"></a> SourceContractErrorType

The stable code for a source contract violation.

```csharp
public const string SourceContractErrorType = "agent_source_contract"
```

#### Field Value

 [string](https://learn.microsoft.com/dotnet/api/system.string)

### <a id="Tracon_TraconAgentSourceException_SourceFailedErrorType"></a> SourceFailedErrorType

The stable code for an ordinary source failure.

```csharp
public const string SourceFailedErrorType = "agent_source_failed"
```

#### Field Value

 [string](https://learn.microsoft.com/dotnet/api/system.string)

## Properties

### <a id="Tracon_TraconAgentSourceException_ErrorType"></a> ErrorType

Gets the stable error type name written to the run record.

```csharp
public override 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 — 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**.

### <a id="Tracon_TraconAgentSourceException_SourceName"></a> SourceName

Gets the stable name of the source that failed.

```csharp
public string SourceName { get; }
```

#### Property Value

 [string](https://learn.microsoft.com/dotnet/api/system.string)
