What causes "wukong commit upload inner failed: %s" in AlistGo/alist?

Retry the whole upload from applyUploadInner with a fresh session and token

wukong commit upload inner failed: %s

Error message

wukong commit upload inner failed: %s

What it means

Thrown by commitUploadInner when the VOD CommitUploadInner action (POST with SessionKey) returns response metadata with a non-empty Error.Code. Commit finalizes the uploaded data on the VOD/TOS side; failing here means uploaded bytes never became a committed object.

Solutions

Retry the whole upload from applyUploadInner with a fresh session and token
Before commit, verify all parts/uploads succeeded (uploadToTOS/multipart finish returned nil)
Refresh auth token right before commit if the upload took long
If the error indicates duplicate commit, re-run uploadSubmit with the previously obtained StoreURI/Vid instead of restarting

Defensive patterns

Strategy: retry

Try / catch

vid, err := d.commitUploadInner(ctx, auth, spaceName, sessionKey)
if err != nil {
    if strings.Contains(err.Error(), "SessionKey") || strings.Contains(err.Error(), "expire") {
        return fmt.Errorf("upload session invalid, restarting full upload: %w", err)
    }
    time.Sleep(time.Second)
    vid, err = d.commitUploadInner(ctx, auth, spaceName, sessionKey)
    if err != nil { return err }
}

Prevention

Only commit after every upload/finish step returned success
Detect 'session expired/invalid' errors and route the user to a full restart instead of blind retries
Refresh auth token before commit on long uploads

When it happens

Trigger: Committing with a SessionKey whose upload was incomplete or aborted; token/signature expired during a long upload; SessionKey already committed (double commit); upstream VOD error while finalizing.

Common situations: Multipart upload that lost parts (network drops) then committed anyway; retry logic re-committing the same session; hour-long uploads exceeding token lifetime.
