Flow Lister for Poshmark: fix start, Amazon, and listing errors
Learn how to fix input errors, Amazon blocks, Poshmark listing limits, and form-filling failures.
On this page
This article lists the messages the Poshmark Flow Lister shows in alerts, the Activity Log, and Listing Activity. Press Ctrl+F (Cmd+F on Mac) to find your message.
Key points
- Input first: Most start errors come from links, ASINs, or a store that wasn't applied.
- Amazon blocks are temporary: Flow Lister pauses and cools down, then tries to resume on its own.
- Poshmark limits are Poshmark's: A listing limit comes from your Poshmark account, not from DropFlowLister.
- Duplicates are skipped: Products already listed in the store are excluded before the run.
Errors before the run starts
"Please enter valid Amazon links or ASINs first."
Cause: The links box is empty or has no usable lines. Fix:
- Paste Amazon product links or 10-character ASINs, one per line.
- Click Validate, then Start Optimization.
"No valid ASINs found in the links. Please check your input."
Cause: None of the lines contain an Amazon product ID. Search pages and short links often don't.
Fix: Use product page links like https://www.amazon.com/dp/B09FCT23B3, or paste the ASIN alone.
"Please select a store and click Apply before starting."
Cause: No store and template are applied. Fix: Pick a store and template, then click Apply.
"⚠️ Store Selection Not Applied!…"
Cause: You changed the store in Select Store but didn't click Apply. Fix: Click Cancel, then click Apply, then start again. If you click OK, the run uses the last applied store.
"Start From value (X) exceeds total links (Y)"
Cause: Start From is higher than the number of items in your list. Fix: Set Start From to 1 or to a number within your list.
"Failed to check for already listed products. Please try again."
Cause: DropFlowLister couldn't reach its server to check for duplicates. Fix: Check your internet connection and start again.
"All N products have already been listed. No new items to process."
Cause: Every product is already listed in this store. Fix: Add new products or pick another store.
"Please configure AI settings before enabling enhancement"
Cause: AI Image Enhancement is on, but no Replicate key, model, and prompt are saved. Fix: Click Configure and finish setup. See AI Image Enhancement troubleshooting.
"Image size must be less than 10MB"
Cause: The background image you uploaded is too big. Fix: Use a PNG, JPG, or WEBP under 10 MB.
Credit and sign-in errors
"⚠️ Bulk Listing Stopped … Please purchase more credits."
Cause: You ran out of credits.
Fix: Add credits, then restart from the next item with Start From. To get more, upgrade your plan or buy a one-time credit pack (see https://dropflowlister.com/pricing/).
"🔑 Session expired — run paused. Sign in again, then press Resume."
Cause: Your DropFlowLister sign-in expired during the run. Fix:
- Open the popup and sign in.
- Go back to the Flow Lister tab and click Continue.
"Product already optimized for this store"
Cause: This product was already processed for this store, so it's skipped. Fix: No action needed. Pick another store if you want it listed there too.
Amazon blocks and cooldowns
"Amazon soft ban detected - CAPTCHA page encountered"
Cause: Amazon showed a CAPTCHA because of heavy traffic from your browser. This is an Amazon limit. Fix:
- Let Flow Lister cool down. You'll see "⚠️ Processing paused - Amazon soft ban detected".
- Complete any CAPTCHA Amazon shows in a tab.
- Use fewer Parallel Threads next time.
"⚠️ Could not auto-resume - please click Resume manually"
Cause: The cooldown ended, but Flow Lister couldn't restart on its own. Fix: Click Continue.
"Skipped: task stalled past watchdog timeout…"
Cause: One product took too long and was skipped so the run could keep going. Fix: Copy unlisted links and run them again later.
Poshmark listing errors
"⚠️ Listing Limit Reached: … your Poshmark account has reached its listing limit…"
Cause: Poshmark won't let your account list more right now. This limit is set by Poshmark, not DropFlowLister. You may also see "Listing limit reached! Stopping all operations." Fix: Stop listing and wait 24 hours before you try again. Poshmark doesn't publish its listing limit.
Note: Running Flow Lister again right away won't get around a Poshmark limit. Waiting is the only fix.
"Failed to fill title", "Failed to set price", or "Listing failed: …"
Cause: Poshmark's listing form didn't respond as expected, often because the page changed or loaded slowly. Fix:
- Make sure you're signed in to Poshmark.
- Copy unlisted links and run them again.
"Failed to upload images" or "No images could be fetched"
Cause: The product images couldn't be downloaded or uploaded. Fix: Open the Amazon page to check that it has images, then retry. Turn off AI Image Enhancement to test whether the AI step is the problem.
"Wrong page detected" or "Error page detected (.oh-my-posh)"
Cause: The Poshmark tab landed on the wrong page or on Poshmark's error page. Fix: Open poshmark.com, check you're signed in, then retry.
"⚠️ No "X" option in Discounted Shipping…" or "⚠️ Pre-submit: still "X" after retry…"
Cause: The shipping discount you picked isn't offered for this listing on Poshmark, or it didn't stick. Fix: Check your Variable Shipping Discount by Cost bands. $4.99 is for poshmark.com, and C$6.99 and C$9.99 are for poshmark.ca.
"Pop-up blocked. Allow pop-ups for this page to open the image."
Cause: Chrome blocked a preview window. Fix: Click the pop-up icon in Chrome's address bar and allow pop-ups for this page.
