Trying to Download macOS Catalina Installer

I am in the process of setting up my late 2013 iMac to boot from an external SSD to improve performance. I am following instructions I found online but I can't get the Catalina installer to download. I click get, it asked if I am sure, I say yes, the progress bar shows that it is 8.25 GB of 8.25 downloaded but errors out before it's done and I don't have the installer in my Apps.

Installation Error: An error occurred while installing the selected updates

I think it is trying to update vs just download and sees that I already have that version?

Is there anything I can change to just get the Installer downloaded so I can install on my external drive?

Follow this help article: Reinstall macOS - Apple Support (i.e., Cmd+R for recovery mode)

The only change in the steps would be you should select your external SSD when prompted to choose "select a disk".

Hope it helps.
