Thrown when a workflow run requires a newer workflow spec version than the installed SDK supports.
RunNotSupportedError is thrown when reading a workflow run whose data was written with a newer workflow spec version than the running SDK supports. This typically means the run was created by a newer version of the workflow package — upgrade the package to process it.
import { RunNotSupportedError } from "workflow/errors"
declare function readRun(runId: string): Promise<unknown>; // @setup
declare const runId: string; // @setup
try {
await readRun(runId);
} catch (error) {
if (RunNotSupportedError.is(error)) {
console.error(
`Run requires spec v${error.runSpecVersion}, world supports v${error.worldSpecVersion}`
);
}
}Properties
| Name | Type | Description |
|---|---|---|
runSpecVersion | number | The spec version the run's stored data requires. |
worldSpecVersion | number | The spec version the current World supports. |
message | string | The error message. |
Static Methods
RunNotSupportedError.is(value)
Type-safe check for RunNotSupportedError instances. Preferred over instanceof because it works across module boundaries and VM contexts.
import { RunNotSupportedError } from "workflow/errors"
declare const error: unknown; // @setup
if (RunNotSupportedError.is(error)) {
// error is typed as RunNotSupportedError
}
