WorkflowRuntimeError
Thrown when the workflow runtime encounters an execution error, such as serialization failures or timeouts.
WorkflowRuntimeError is thrown when the workflow runtime encounters an error executing a workflow. Common causes include:
- Values crossing the workflow/step boundary that cannot be serialized
- Workflow execution timeouts
- Invalid runtime state, such as misconfigured streams
import { WorkflowRuntimeError } from "workflow/errors"
declare function runWorkflowOperation(): Promise<void>; // @setup

Static Methods
WorkflowRuntimeError.is(value)
Type-safe check for WorkflowRuntimeError instances. Preferred over instanceof because it works across module boundaries and VM contexts.
import { WorkflowRuntimeError } from "workflow/errors"
declare const error: unknown; // @setup
if (WorkflowRuntimeError.is(error)) {
// error is typed as WorkflowRuntimeError
}
