I'm using Apache Tika to detect a file Mime Type from its base64

obtain a more specific information: "application/json",
"application/pdf" etc...
You can't detect JSON files from mime magic alone - json doesn't have
anything unique at the start, just lots of possible different things which
also occur in other formats too
Tika can detect a PDF from the magic bytes at the start just fine. Make
sure you're actually decoding the base64 representation properly
