Reporting an issue: App Proxy page not rendering for some stores

I’m reporting an issue that had been affecting our app’s App Proxy page.

The issue seems to be resolved as of yesterday, but we are not sure what the cause was since the issue went away without us doing anything.

The issue was that our App Proxy page wasn’t rendering for some stores (not all) giving the error “Minified React error #130”.

I’m afraid that I cannot provide the details of the error since it’s gone now.

I’m speculating that this had something to do with Shopify’s server. (perhaps SSR?)

(Our App Proxy page uses Next.js 11, and it is served on Google App Engine.)

The information above is probably not enough to debug the issue. But I hope I’m providing enough information for Shopify to recognize what might have been going wrong.

Please feel free to ask if I need to clarify something, or provide other information.

If you are indeed talking about app proxies, what I have noticed is that if you have (for instance) your production app installed in a test store, and then also install your development app, so basically you have two apps competing for the app proxy, the latter one will become something like /apps/api-1 and things don’t work.
