What causes "the task has been deleted" in AlistGo/alist?

Treat the terminal status as final and remove the local task record

the task has been deleted

Error message

the task has been deleted

What it means

Thunder.Status() returns a status pre-seeded with 'the task has been deleted' and s.Err set; it is only replaced when task.GID is found among the remote Thunder tasks. A fall-through return therefore marks the task as terminally failed because it no longer exists on Thunder's side.

Solutions

Treat the terminal status as final and remove the local task record
Re-add the URL if the content is still required
Clear stale task records after re-authenticating the Thunder storage

Example fix

s, err := t.Status(task)
if err == nil && s.Err != nil && strings.Contains(s.Err.Error(), "has been deleted") {
    _ = deleteLocalTask(task.ID) // remote task gone, stop polling
}

Defensive patterns

Strategy: fallback

Try / catch

s, err := t.Status(task)
if err != nil {
    return err
}
if s.Err != nil && strings.Contains(s.Err.Error(), "has been deleted") {
    markCompletedAndCleanup(task)
}

Prevention

Check s.Err alongside err — deletion is reported via the status object
Avoid deleting tasks in the Xunlei app while tracked here
Clear stale records after Thunder account re-login

When it happens

Trigger: The Thunder offline task was deleted remotely (app/web cleanup), expired, or belongs to a re-linked account whose task IDs no longer match task.GID.

Common situations: Users deleting downloads from the Xunlei app; account re-login invalidating old task IDs; the platform pruning completed tasks after retention.
