Key points

  • Check the supplier tab first. Most stops mean the supplier page needs one click or a quick fix from you.
  • You can always finish by hand. If Auto Order stops, complete the checkout yourself. Nothing is lost.
  • Supplier checks are the supplier's. Captchas, purchase limits, and address checks come from the supplier, not from DropFlowLister.

Before you start

  • Refresh the eBay order page and the supplier page.
  • Sign in to eBay, to the extension, and to your supplier account in the same browser.
  • Open the full order details view on eBay, not the order list.

"No SKU on this page"

Cause: The order page doesn't show the listing's SKU (Custom label).

Fix:

  1. Click Get SKU on the panel, if it shows.
  2. If there's still no SKU, add one to the listing in eBay. Use the supplier product ID (for example the Amazon ASIN).

"Could not decode SKU "X" to a product" / "… to a valid ASIN"

Cause: The SKU isn't in a format Auto Order can read. Auto Order reads plain Amazon ASINs and the coded SKUs DropFlowLister creates when it lists.

Fix: Use Product Link if it works, or open the supplier product yourself. Fix the SKU on the listing for next time.

"No shipping address found on this page" / "No buyer shipping details found on this page — open the full order details view and try again"

Cause: The address isn't visible on the page you're on.

Fix:

  1. Open the order's full details page in Seller Hub.
  2. Click Place Auto Order or Copy Buyer again.

"Pick a delivery date first"

Cause: You clicked Copy Message before choosing a delivery date for the ETA message.

Fix: Choose the date in the panel, then click Copy Message.

"Saved on this PC only — sign in to DropFlow to use it on your other PCs."

Cause: Copy Buyer worked, but you aren't signed in, so it didn't sync to your account.

Fix: Sign in to the extension if you want to click Import Buyer on another computer.

"ASIN mismatch detected"

Cause: The supplier page now shows a different product than the one the SKU points to. The supplier may have changed or merged the listing.

Fix:

  1. Compare the Expected ASIN and Page ASIN shown.
  2. Continue only if it's the same item the buyer paid for.
  3. Otherwise, find the correct product and order it yourself.

"⚠️ Coupon could not be clipped automatically"

Cause: The page has a coupon, but Auto Order couldn't clip it.

Fix: Clip the coupon yourself on the page, or click Continue without coupon.

"Buy Now not found — using Add to Cart" / "Could not trigger purchase"

Cause: The supplier page has no Buy Now button. The item may be out of stock, need a size or color, or be sold only through the cart.

Fix:

  1. Pick any needed option on the page.
  2. Click Buy Now or Add to Cart yourself.
  3. Finish checkout by hand.

"Missing buyer data — aborting fill" / "Could not finalize address — please complete manually" / "Change address link not found"

Cause: Checkout opened, but Auto Order couldn't fill or confirm the address.

Fix:

  1. On the supplier checkout page, open the address form.
  2. Click Import Buyer if you used Copy Buyer, or type the address.
  3. Save the address and finish the order.

"Place Order failed"

Cause: The final click didn't go through. The supplier may want a payment check or a confirmation.

Fix: Look at the checkout page, fix anything it asks for, and click Place Order yourself.

"Page failed to load — please reload manually"

Cause: The supplier page didn't finish loading.

Fix: Reload the page. Auto Order continues if the order is still pending, or you can finish by hand.

AliExpress: "Buy Now button not found" / "Pay Now button not found" / "Address form did not close — validation likely failed"

Cause: AliExpress needs an option chosen, or it rejected part of the address.

Fix:

  1. Choose any required option and click Buy Now yourself.
  2. Check the address form for red errors and fix them.
  3. Click Pay Now yourself.

Walmart: "Walmart needs you to fix this"

Cause: Walmart showed an error on the checkout page, such as an address or payment problem. The details appear under the message.

Fix: Read Walmart's message, fix it on the page, and finish the order.

"Could not save to bookkeeping: …" / "Queued locally for retry (N pending)"

Cause: The order was placed, but the sale couldn't be saved to Bookkeeping. The extension keeps a copy in this browser.

Fix: Check that you're signed in. Then see Bookkeeping troubleshooting.

Chrome says the extension "started debugging this browser"

Cause: This is normal. Auto Order uses Chrome's debugger to click Amazon buttons the way a person does.

Fix: No action needed. Don't click Cancel on the bar while an order is running, or the click step will stop.
