Understanding your integration Activity Log (errors explained)
What the errors in your Sign Customiser Activity Log mean — including which ones are harmless and which need action.
Last updated:
Your Shopify Sign Customiser app keeps an Activity Log of the calls it makes to Shopify when it creates your custom sign products and adds them to the cart. When you switch the log to Errors Only you may see a count such as “3 errors in the last 7 days”.
Not every entry in the “Errors Only” view means something is broken. Some entries are informational skips that the app records for transparency — your customers were not affected and your products were still created. This guide explains the most common entries.
Where to find it
-
In your Shopify admin, open the Sign Customiser app.
-
Open your integration and look at Activity Logs.
-
Use the Errors Only filter, then click View Details on any row to see the full request and response.
“Shopify market publication lookup skipped” (status 424) — harmless
This is the most common entry and it is benign. It means your custom product was created and published to your Online Store normally. The app also tried to publish it to a specific Shopify Market, but no market information was supplied for that request, so it simply skipped the optional market step.
You typically see this if your store doesn’t use Shopify Markets, or your storefront (for example a headless or custom theme) doesn’t pass the shopper’s active market to the customiser. No action is needed — your products and orders are unaffected.
This is not the “Missing Permissions” issue. Even though the message mentions publishing, it is not the required Publications permission, and you do not need to accept any new permission to clear these entries. Only follow Missing Permissions if you are actually told that a required permission is pending.
The only time to act on this is if add to cart fails for shoppers in certain countries — see Why is add to cart not working? for the Shopify Markets setup.
“Missing Permissions” (status 401 or 403) — action needed
If the log shows a permission-denied response, or your customisers display a Missing Permissions message, Shopify is waiting for you to accept a required permission. Open the Sign Customiser app in your Shopify admin and accept the new permission when prompted. Full steps in Missing Permissions.
“Too many variants” (status 422 or 429) — action needed
Stores not on Shopify Plus can add up to about 1,000 new variants per day. When that limit is reached, new custom products cannot be created until it resets. See Why is add to cart not working?
“Out of stock” or location fulfilment (status 422) — action needed
If your default location does not have fulfilment or shipping zones configured, adding a custom product to the cart can fail as “out of stock”. See the location and shipping steps in Why is add to cart not working?
Server errors on custom or WordPress stores (status 5xx) — action needed
For non-Shopify integrations, a 500 or other 5xx status means your own server rejected the request. Open View Details to read the exact error returned by your site, then check your platform’s logs.
Still not sure?
Open View Details on the error, copy the description and the status code, and send them to us via the in-app chat. Our assistant can read your logs directly and tell you the exact cause. Please don’t rely on the “errors” count alone — the details tell the real story.
