First solution:

It is reported that this error occurs during the installation of macOS Catalina if the Internet connection is interrupted or disconnected.

Make sure that the Mac has an active wi-fi or ethernet connection and that the Internet works as expected, and then try to install macOS Catalina again.

Second solution

The Recovery Mode installer of Catalina appears to not be able to properly partition the drive.

Install High Sierra or earlier macOS from Recovery Mode and then upgrade to Catalina or install Catalina (or High Sierra) from a bootable drive.
