Thrown when creating a hook with a token that is already in use by another workflow run.
HookConflictError is thrown when creating a hook with a token that is already in use by another active workflow run. Hook tokens must be unique across all running workflows — see the hook-conflict error guide for resolution strategies.
import { HookConflictError } from "workflow/errors"
declare function startApprovalWorkflow(token: string): Promise<void>; // @setup
declare const token: string; // @setup
try {
await startApprovalWorkflow(token);
} catch (error) {
if (HookConflictError.is(error)) {
console.error(
`Token "${error.token}" already in use by run ${error.conflictingRunId}`
);
}
}Properties
| Name | Type | Description |
|---|---|---|
token | string | The hook token that conflicted. |
conflictingRunId | string | The run ID of the workflow currently holding the token, when known. |
message | string | The error message. |
Static Methods
HookConflictError.is(value)
Type-safe check for HookConflictError instances. Preferred over instanceof because it works across module boundaries and VM contexts.
import { HookConflictError } from "workflow/errors"
declare const error: unknown; // @setup
if (HookConflictError.is(error)) {
// error is typed as HookConflictError
}
