Expected behavior: there should not be any exception and conversions should be made.
Note: after checking the code here, this means the blob passed as parameter seems to be null. This may indicate that the soffice command did not return anything and its behavior has changed in 6.x version.
Trying the same scenario with the latest 5.x version (5.4.7.2) works fine.
