When calling newContent with a binary file, you end up with a lot of null values warning in the logs

[eborisowIQVIA]

When you use code like the following:
context.newContent(input.getId(), new FileInputStream(workFile))
.fields(f -> f.merge(candidateFields))
.emit();

where workFile is a binary file, you get a lot of warnings depending on the file type. In the case of Excel files, you end up with a lot of messages like this:
invalid object type:null for key:clrMapOvr.masterClrMapping

Is there any way to stop these error messages from appearing?
