Updating the argument in already scheduled Cron job

Community Support
1

We have scheduled one monthly job. Is there a way to update the arguments in already scheduled and running Cron job?

const handle = await client.start(cronStartFunc, {
  args: [payload],
  taskQueue: 'my-queue',
  cronSchedule: '0 0 1 * *',
  workflowId: `${nanoid()}`
});

Is there a way to update the arguments(args) from the next run onwards ?

This isn’t supported with the cron feature but is supported by the newer “schedules” feature.

See the API reference how to use it and samples in the SDK test suite:

Note that schedules requires Temporal server >= 1.18 and are not yet available on Temporal Cloud.
