I'm currently developing a Liferay portlet that can upload some pdfs and png to the Documents and Media Repository in Liferay DXP 7.4.13 u33. I'm trying to use the static method addFileEntry from the class DLFileEntryLocalServiceUtil. Either in its normal or deprecated mode it's not working.
I have also tried with DLAppLocalServiceUtil.addFileEntry(externalReferenceCode, userId, repositoryId, folderId, sourceFileName,mimeType, urlTitle, description, changeLog, file, expirationDate, reviewDate, serviceContext) but I got the same result.
Im getting the following errors from this request, when I call this method via an MVCActionCommand in my portlet:
