The current import operation is already finished.

Error message

The current import operation is already finished.

What it means

Thrown by assertsValidStateForNewData when the last import operation is in a terminal state: 'done', 'error' or 'canceled'. Once an import finishes (successfully or not), the operation record is closed and cannot receive new data; a fresh operation must be started instead.

Solutions

1. Start a new import operation rather than reusing the finished one
2. Check operation.state before uploading and branch to the start flow when it is terminal
3. Clear client-side references to the old operation after completion

const op = await Imports.findLastImport();
if (['done', 'error', 'canceled'].includes(op?.status ?? '')) {
  throw new Error('operation finished; start a new import');
}

function isTerminalImportState(state: string | undefined): boolean {
  return state === 'done' || state === 'error' || state === 'canceled';
}

When it happens

Trigger: Calling addUsers(...) after run() completed with state 'done'; retrying an upload against an operation that ended in 'error'; adding data to an operation the user canceled.

Common situations: Retrying a failed import by re-uploading into the same operation instead of starting a new one; background jobs that keep feeding a completed migration; canceled imports leaving stale client state.
