I have no idea what's going on. I'm trying to write my assignment in Latex but the references are not showing up. I put this on the preamble:

\usepackage{biblatex}
\addbibresource{ref.bib}

My folder is split into different files, so I have this on the main file:

\import{sections/}{Referencias}

And in the file Referencias.tex I have this:

\section*{\centering REFERÊNCIAS}
\printbibliography

My file ref.bib has the Biblatex reference like so:

@book{NISE:2013,
  author    = {Norman S. Nise}, 
  title     = {Engenharia de sistemas de controle},
  publisher = {LTC},
  year      = {2013},
  address   = {Rio de Janeiro},
  edition   = {6},
}

@book{OGATA:2010,
  author    = {Katsuhiko Ogata}, 
  title     = {Engenharia de controle moderno},
  publisher = {Pearson Prentice Hall},
  year      = {2010},
  address   = {São Paulo},
  edition   = {5},
}

@misc{Deepanshu:2016,
  author = {Deepanshu Singh, Himanshu Jain }
  title = {Reinforcement Learning},
  howpublished = {\url{http://courseprojects.souravsengupta.com/cds2016/reinforcement-learning/}},
  note = {Accessed: 2019-04-14}
}

and I cite it like this:

\cite{Deepanshu:2016}

But the references won't show up. If anyone could give me a hand or point me in the right direction it would be greatly appreciated, because honestly, I don't even know what to Google to solve this.

EDIT

So, this is the output of my .blg file:

  • Did you run the normal cycle: pdflatex > biber > pdflatex (twice)? – Bernard Apr 20 '19 at 20:37
  • I've simply compiled with the Overleaf compile button, is that it? – João Areias Apr 20 '19 at 20:39
  • I don't know Overleaf, so I can't tell. Do you have a .bbl and a .blg files? – Bernard Apr 20 '19 at 20:45
  • no, are they generated when compiling? Sorry, this is my first time using biblatex. – João Areias Apr 20 '19 at 21:01
  • The entry Deepanshu:2016 is malformed. There are two issues: (1) Multiple names must be separated with an and not a comma, regardless of the desired output (https://tex.stackexchange.com/q/36396/35864). (2) There must be a comma after the field (it is omissible after the last field in an entry). So you should have author = {Deepanshu Singh and Himanshu Jain},. This will definitely stop this entry from showing up, but the others should be displayed. – moewe Apr 20 '19 at 21:06
  • You should also be using the url and urldate field instead of howpublished and note: url = {http://courseprojects.souravsengupta.com/cds2016/reinforcement-learning/}, urldate = {2019-04-14}, – moewe Apr 20 '19 at 21:06
  • Fix the two errors mentioned in my comment above. Then recompile your project from scratch, see https://tex.stackexchange.com/q/479736/35864. Then you can access the .blg file as described in https://tex.stackexchange.com/q/462314/35864 for the .bbl file. Download the .blg and the .log. Post the complete .blg here and post all parts of the .log that mention warnings or errors. – moewe Apr 20 '19 at 21:09
  • Ok, I've fixed the errors and posted the .blg and .log – João Areias Apr 20 '19 at 21:44
  • Solved, damn you freaking comma!!!! – João Areias Apr 20 '19 at 22:20

I solved thanks to the comments and just wanted to leave it here if it is of any help. As one can see in the .blg file it was missing a comma after author in the .bib file. I could not have noticed it by compiling with overleaf since I can't see this file from there, I solved it, compiled from scratch and it works like a charm, but for some strange reason the same fix does not work on overleaf.
