When opening a document with OnlyOffice V6.2 the following error message appears:
The "documentType" parameter for the config object must take one of the values word/cell/slide.
This seems something that has to be fixed from the Seafile Server side if I’m not mistaken.
Furthermore documents seem to stay locked even when closing the OnlyOffice document editor (single and multi user edit all left the session for more than 15 min). The documents seem to have been saved to Seafile though.
