    Class ViolationError<T>

    ViolationError represents errors that require explicit handling in the system. These are distinct from recoverable errors that can be automatically handled by workflow logic. The explicit handling may be required for severe violation of service contracts or explict retry handling

    Common violation scenarios include:

    • Execution error like rate limit exceeded on external API calls
    • Contract violations (invalid input/output)
    • Configuration errors
    • Permission/authorization failures

    Type Parameters

    • T extends string = string

    isArvoViolationError: true

    An additional flag to determine if it is an Arvo specific violation error

    message: string
    metadata: Record<string, any> | null

    Additional structured data about the violation

    name: `ViolationError<${T}>`

    The error name, formatted as ViolationError This helps with error identification in logs and stack traces

    stack?: string
    type: T

    The specific type/category of the violation

    stackTraceLimit: number

    The Error.stackTraceLimit property specifies the number of stack frames collected by a stack trace (whether generated by new Error().stack or Error.captureStackTrace(obj)).

    The default value is 10 but may be set to any valid JavaScript number. Changes will affect any stack trace captured after the value has been changed.

    If set to a non-number value, or set to a negative number, stack traces will not capture any frames.

    Methods

    • Creates a .stack property on targetObject, which when accessed returns a string representing the location in the code at which Error.captureStackTrace() was called.

      const myObject = {};
      Error.captureStackTrace(myObject);
      myObject.stack; // Similar to `new Error().stack`

      The first line of the trace will be prefixed with ${myObject.name}: ${myObject.message}.

      The optional constructorOpt argument accepts a function. If given, all frames above constructorOpt, including constructorOpt, will be omitted from the generated stack trace.

      The constructorOpt argument is useful for hiding implementation details of error generation from the user. For instance:

      function a() {
      b();
      }

      function b() {
      c();
      }

      function c() {
      // Create an error without stack trace to avoid calculating the stack trace twice.
      const { stackTraceLimit } = Error;
      Error.stackTraceLimit = 0;
      const error = new Error();
      Error.stackTraceLimit = stackTraceLimit;

      // Capture the stack trace above function b
      Error.captureStackTrace(error, b); // Neither function c, nor b is included in the stack trace
      throw error;
      }

      a();

      Parameters

      • targetObject: object
      • OptionalconstructorOpt: Function

      Returns void
