An error might occur after a while when deploying the definitions. By default, Azure Web Apps timeout is set to 230 seconds. This causes Azure to abort with a 500 error any request that does not send a response back to the client in the specified time frame. However, even if the request is aborted by Azure, and the error is shown in UI, the process is still running in the background, and there is no easy way to know when it finishes.
To resolve the issue, consider one of the following options:
Be aware that these hotfixes were built for specific Sitecore XP versions, and must not be installed on other Sitecore XP versions or in combination with other hotfixes. In case any other hotfixes have already been installed on a certain Sitecore XP instance, send a request for a compatibility check to Sitecore Support.
Note that the ZIP file contents must be extracted to locate installation instructions and related files inside. The hotfixes must be installed on a CM instance and then synced with other instances using standard development practices.
