PDFs in Datastore for Agent Builder are not getting Indexed

[acapone]

I am using the Agent Builder and creating a datastore of PDFs, but I keep getting an error that says the PDFs are not getting indexed. Has anybody been able to get past this before?

Here is the full log of the error, it is the same for every PDF that I have in the datastore:
