Failed to re-run job

Error message

Failed to re-run job ${id}.

What it means

The 'wmill job rerun' command attempts to rerun each given job id (or a file of ids), collecting failures. If every rerun attempt failed so that no new job ids were produced, it throws this error naming the original job id.

Solutions

1. Read the errorLines printed just above — they contain the per-id server error and point to the root cause
2. Verify the job id exists in the target workspace ('wmill job list' or UI) and the script/flow still exists
3. Check your token/workspace has permission to create new runs
4. Retry the rerun for a subset of ids to isolate which ones work

Example fix

// before
wmill job rerun deadbeef  # script deleted -> fails
// after
wmill job list | grep deadbeef  # confirm job & script exist
wmill job rerun <valid-id>

// confirm the job and its runnable still exist before rerun
const job = await wmill.getJob({ workspace, id });
if (!job) throw new Error(`Job ${id} not found in workspace`);
const runnable = job.script_path
  ? await wmill.getScriptByPath({ workspace, path: job.script_path }).catch(() => null)
  : null;
if (job.script_path && !runnable) throw new Error(`Script ${job.script_path} no longer exists`);

try {
  await wmillJobRerun(id);
} catch (e) {
  if (String(e).includes("Failed to re-run job")) {
    console.error(`Rerun of ${id} failed entirely; check the per-id error lines printed above and that the script/flow still exists`);
  }
}

When it happens

Trigger: Rerunning a job whose run cannot be recreated server-side: the underlying script/flow was deleted, the job id is wrong, the job type isn't rerunnable, or the workspace token lacks permission — for all provided ids so newIds ends up empty.

Common situations: Rerunning after the script was deleted or renamed; stale job id copied from another workspace; token without write permissions; rerunning a large ids file where every line failed (the errorLines above list why).
