We understand that this plugin automatically adds the references extracted from an article to the DOI record with Crossref, and that Crossref then checks whether a DOI can be found for the submitted references.
According to the information provided by Crossref, there seems to be an error in the communication between the plugin and Crossref: Crossref Link.
We reached out to Crossref for clarification, and they informed us that this issue is due to a bug in the OJS plugin’s code, which is something beyond our control and falls under PKP’s responsibility.
We would like to know if there is any planned update or if you have any information on when this issue might be resolved.
OJS 3.4.0-8
