Rejecting the request would be ok.
If you are trying to minimize failure cases then ignoring this might
give you a chance for the message to work. IMO the header with no value
is plausibly the same as no header, even though it is a syntax violation.
If you ignore, and there is no body, then all should be fine.
If you ignore and there is a body then you will want to assume the
default type, which depends on the message. For INVITE, etc. this is
application/sdp.
