unexpected EOF while making a search Compact

[sredxny]

Hello, cheers! I am facing a repetitive problem while am pulling data using gorets. I don't know if it's gorets related, HTTP or my implementation. The problem is that in some request after I make a SearchCompact then am getting unexpected EOF

The logs of the search is as follows:

And the last data retrieved is as follows https://pastebin.com/raw/7ck2ndgs

So, where may I be failing? or how can I avoid this and get all the data?
