@dosubot[bot] commented on GitHub (Dec 25, 2024):

I found a similar closed issue titled "Creating an app from a Template causes a 404 error [SELF_HOSTED]" which was resolved by a pull request that fixed an error related to importing Explore Apps [1]. Although this issue was specific to a 404 error, it might be related to the "App not found" message you're encountering.

The 'App not found' message in Dify is triggered by the AppNotFoundError class, which results in a 404 HTTP status code. This error is typically shown when an application cannot be found [2].

In your case, since the app is actually created successfully despite the error message, it might be a temporary glitch or a UI issue that doesn't affect the actual app creation process. You might want to check if there are any recent changes or updates in the Dify codebase related to error handling during app creation, as these could potentially address the issue.

The version and error message are different; it seems the issue has reappeared after the update.
