I'm following How to create a bootable installer for macOS guide by Apple, but it's giving me an error. When I execute

sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/disco

It gives me this:

dyld: Library not loaded: @executable_path/../Frameworks/IAESD.framework/Versions/A/IAESD
  Referenced from: /Applications/Install macOS Catalina.app/Contents/Resources/createinstallmedia
  Reason: no suitable image found.  Did find:

I'm using OS X Yosemite 10.10.5 on a Macbook Pro 2015.

The USB device is a 1TB External Hard Drive, Mac OS Extended formatted.

    You need to re-download the installer. Also, don't you have a 16GB USB flash anywhere? a 1TB USB drive is awfully huge and will take forever to partition, format and image.

In recent versions of the installers, they have a special version of createinstallmedia in the same folder called createinstallmedia_yosemite that takes the same arguments as the other. I don't have Yosemite to test this, but I'd place my money on that one being the one to use.

Example location of this executable in installer: "Install macOS Monterey.app/Contents/Resources/createinstallmedia_yosemite"

Installer files might be not available in the installer

Proceed with https://apple.stackexchange.com/a/307118

UPD: so even after processing steps you still receive such error. The problem is because of macos yosemite. When using the same app on 10.14 it works. Don't known, maybe some earlier versions would also work.
