Error while downloading installer

I have a 13” mid-2012 MacBook Pro with 16GB RAM, 292 GB available storage, and a 32 GB thumb drive that I plan on using for the installation.

I’m trying to update to Sonoma 14.7.1 and I get this error whenever I try to download the installer (this also happens whenever I try to download Monterey 12.7.4 and Ventura 13.7.1)

Any reasons as to why this is happening and is there any way to fix this?
