I have many org roam files with the following format

```auto
:PROPERTIES:
:ID: 9e434546-09b9-46a3-bfe5-3e1d01344f1e
:ROAM_REFS: cite:FOCS:LinLonRab94
:END:
#+TITLE: 1994 - [FOCS:LinLonRab94] - The geometry of graphs and some of its algorithmic applications
#+FILETAGS: paper FOCS

```

But org roam report the following warnings:

```auto
Warning (org-roam): /Users/junwei/github/org/roam/biblio/C:AnaJai15.org:1	Invalid ref cite:C:AnaJai15, skipping... Disable showing Disable logging

```

Anybody could explain what could go wrong? Many thanks.

You need to load org-ref.
