Data get entity command crash

Using "/data get entity ..." without specifying a path crashes my game in multiplayer with this message:

Internal Exception: io.netty.handler.codec.DecoderException:
java.lang.IndexOutOfBoundsException: readerIndex(1) + length(1) exceeds writerIndex(1):
PooledUnsafeDirectByteBuf(ridx: 1, widx: 1, cap: 1)

Tried to find a matching bug report because I thought for sure people were playing with the new /data command in the pre-release. I know I've been loving playing with it in the snapshots before in single player.
