It’s better for the TokenProgram parser to use
unpack_from_sliceinstead ofunpack, otherwise it may fail on uninitialized accounts. The handlers should be responsible for dealing with that logic.I also replaced the
"Invalid Account data length"error withErr(ParseError::Filtered)because the previous message was generating a lot of noise due to the large number of accounts with incorrect lengths.
