Error HTTP 500 when using oc_coci_cites

[JosefinaW]

Hello,

I am just starting with using this package and I get this error when trying the oc_coci_cites("10.1108/jd-12-2013-0166"): Error: Internal Server Error (HTTP 500).

• The server encountered an unexpected condition which prevented it from fulfilling the request.
  oc_coci_meta works fine for me.

Any guidance would be appreciated!

Thank you,

Josefina
