minLength error

[bolelligallevi]

Hi Dulip, I received this error for a doi registration by the plugin:
2021-01-26 15:27:01.730 ERROR 37 :: DOI 10.13130/unimi2040.37: [facet 'minLength'] The value has a length of '0'; this underruns the allowed minimum length of '1'. at line 20, column 0
Due to this error, no DOI was created in datacite, but in the plugin the submission was moved to Deposited tab anyway.
The error seems to refer to a specific field as written in the XML sent to datacite, unfortunately I can't provide it because of the delete operated by the plugin (DataciteExportPlugin.inc.php row 183).
I looked for relevant missing fields in the submission, but I didn't find any.
We commented the delete part of the code and we'll try some other tests, but I wanted to ask:

• if is possible to have more details from datacite about the issue (the datacite OJS plugin provide them)
• why the plugin moves the submission to the deposited tab despite no registration in datacite.
  best regards
  Stefano

Hi,

we just experience the same error as mentioned here. Any ideas what causes this and how to solve it?

Yours,

Just found the solution (by examining the resulting XML files): We did not enter a publisher, so the publisher tag was empty.

As of now, publisher identity is stated to be obligatory only if one needs ONIX-Metadata. So maybe clarify that at least the name of the publisher is needed for DataCite DOIs as well.

Yours
