We’re seeing the same thing on our end. The error pops up randomly in our logs, but no merchants have actually reported any issues or complained about it. It seems intermittent and doesn’t appear to affect functionality in any meaningful way. Would love to know if the Shopify team has any insight into what’s causing it.
Thanks for flagging this error - it does appear to be an issue on our side, we’re investigating a fix for this. Will update here when there’s more to share.
We see this sometimes but it’s usually when it takes a really long time for app-bridge.js to load. I assumed it was a temporary networking hiccup where they aren’t able to download the file from the Shopify CDN
