Persistent "Unable to fetch app definition" Error on App Creation (Even Blank + Simple Data)

AppSheet AppSheet Q&A
1

Hello AppSheet Team,

I am encountering a persistent error when creating AppSheet applications, which prevents the editor and preview from loading successfully.

Problem Description: After creating an app (either by connecting existing data or by creating a blank app and then adding data manually), the app preview consistently displays the following error:

Error
The [AppName-xxxxx] app did not load successfully. Please contact the app creator.
Unable to fetch app definition. App '[AppID]' version '1.00000x' is not runnable -

The issue does not seem related to data complexity or the specific Google account used. It occurs even in the simplest possible scenario (blank app + new basic spreadsheet) across two different Google accounts.

This strongly suggests a potential issue with the AppSheet platform itself during the initialization phase of the app definition within my environment.

Could you please help with this issue?

I’m afraid you need to give more information from your app and datasource. The reason can be whatever and it’s difficult to say e.g. without seeing your app. You could also contact support so they could check what’s wrong.
