Class: WorkflowExecutionAlreadyStartedError

common.WorkflowExecutionAlreadyStartedError

This exception is thrown in the following cases:

• Workflow with the same Workflow ID is currently running and the WorkflowOptions.workflowIdConflictPolicy is WORKFLOW_ID_CONFLICT_POLICY_FAIL
• There is a closed Workflow with the same Workflow Id and the WorkflowOptions.workflowIdReusePolicy is WORKFLOW_ID_REUSE_POLICY_REJECT_DUPLICATE
• There is closed Workflow in the Completed state with the same Workflow Id and the WorkflowOptions.workflowIdReusePolicy is WORKFLOW_ID_REUSE_POLICY_ALLOW_DUPLICATE_FAILED_ONLY

stackTraceLimit

▪ Static 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

captureStackTrace

▸ captureStackTrace(targetObject, constructorOpt?): void

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();
