Error when trying to sync; New Account, library, and install

zlambers
Hello,
I and my group are using Zotero for our Senior Engineering Project. I have created a new Zotero account and followed the steps for setting it up. However, when trying to sync things that I have saved on my Zotero desktop app I get a red exclamation mark in the top right corner (error contents and report ID at bottom of post).

I only have a couple things in my library currently a patent from google patents (with the pdf of the patent), an engineering textbook from the Purdue Library, and a couple pages from the Zotero discussion forum. I saved everything using the firefox addon.

I have checked my sync settings and I am signed in properly on my desktop app. I am only using the firefox add on to save things (I don't have chrome on this computer). This is currently the only computer that I am using for Zotero.

The two pages from the forum that I saved from the forum synced to my cloud while everything else did not.

Any help is appreciated thank you.
