[SOLVED] [OJS 3.1] Crossref validation error

Software Support
1

Dear all,
Yesterday I tried submitting to crossref for doi registration and I got this error:

Validation errors:

Element '{http://www.crossref.org/schema/4.3.6}journal_volume': This element is not expected. Expected is one of ( {http://www.crossref.org/schema/4.3.6}contributors, {http://www.crossref.org/schema/4.3.6}publication_date ).

Could not convert selected objects.

My xml output is here:
https://pastebin.com/ZVjiyXsJ

Then I deleted the following lines and submitted manually from crossref webiste (successfully):

<journal_issue>
        <journal_volume>
          <volume>5</volume>
        </journal_volume>
        <issue>2</issue>
      </journal_issue>

Last time I successfully submitted from OJS interface was on July 22, 2017 before upgrading to OJS 3.1.

I would like to know if I have some problem in my system or is there some problem with OJS configuration of crossref requirement. And, how to solve it.

Regards,

Hi @anupent,

Is it because you are missing the publication date element for the issue? I think publication_date (year) is required (Required, Recommended, and Optional Elements – Support Center).

Thanks @astevens for your reply.

You clinched the diagnosis. I had not entered the date as I was publishing it as “Ahead of Print” issue.

Ah-ha! I’m glad it was an easy fix.

I’m facing the same error with DOI while trying to publish the issue in advance of print. May I know if I should not enter the publishing date to sort out the problem?
