H-1B consular notify petition RFE

Hi everyone, So I am currently on a TN Visa working within the US with company A and my future employer company B filed an H-1B consular notify petition for me in April in which I was selected in the lottery, but I received an RFE a few weeks back and I was wondering since we haven’t received the RFE in the mail as of yet, if anyone knew from experience what kinds of RFE’s are usually asked for during a “consular notify petition” ?

Thanks in advance.
