[OJS 3.1.2.4] Copernicus Export Plugin Error Date

[diegomejia071]

Hi,

I installed the Copernicus Export Plugin, and did the XML validation before exporting it, to upload it to the Index Copernicus platform. The validation in the OJS of the XML is shown well and valid, but when uploading it to the Index Copernicus platform, it shows me an error, since the publication date format, as it is exported from the OJS, is not valid.
