OJS 3.1.2.4

Hello,
When trying to export certain articles the page generates an error http 500.
Unfortunately I did not find an answer in the forum.
Below the apache error log.

[php7:notice] [pid 514] PHP Notice: Undefined offset: 0 in /lib/pkp/plugins/importexport/native/filter/SubmissionFileNativeXmlFilter.inc.php on line 79, referer: management/importexport/plugin/NativeImportExportPlugin

Thank you for now.

Hi @Tineu,

I think the issue is related to the missing file warning you received. It says that the file /files/journals/20/articles/4105/4105-13-12023-1-0-20200810.docx doesn’t exist or can’t be read. If that file really is missing, you can put a placeholder .pdf file in its place.

In fact, it didn’t exist at all.
What existed in the place was practically the same file with the slightly different name.
4105-13-12023-1–20200810.docx
The file name did not contain “0” with only 2 dashes “-”.
I made a copy of the file and renamed it to the correct name.
The problem was corrected and thankfully it only occurred on 3 occasions.

I appreciate the attention.

Felipe.
