"The format of the update config file is incorrect" error when running the mobile application

"The format of the update config file is incorrect" error occurs when you run the mobile application with the "Check for Workspace Update" option enabled, while some required settings cannot be obtained from PowerServer AEM.

Solution 1: Please turn off the "Check for Workspace Update" option if you are sure the app should not be updated via PowerServer AEM. This usually happens when you install and plan to update the app via the third-party server or other channel.

Solution 2: If you have the "Check for Workspace Update" option enabled and plan to update the app automatically via PowerServer AEM, please double check that the installer file of the same mobile app (it can be higher than, equal to, or lower than the current version) exists on the PowerServer AEM. You may need to make sure that the installer file name is in the correct format before you upload the file to PowerServer AEM. For how to upload the file to PowerServer AEM, refer to the section called “Upload standalone mobile apps and Appeon Workspace” in PowerServer Configuration Guide for .NET or in PowerServer Configuration Guide for J2EE.
