Using ReedSolomon library to erasure code a file

Question

Using [ReedSolomon JavaScript Library][1] to erasure code a local file, it gives me following error :

shardSize 5432
bufferoffset 0
bufferSize 5432
paritysize 10864
sources 3
targets 12
/Users/nidhisharma/client-sdk/Node/0chain_sdk/encode.js:56
 var rs = ReedSolomon.encode(
                      ^

Error: shardSize % 8 != 0

    at startup (internal/bootstrap/node.js:279:19)
    at bootstrapNodeJSCore (internal/bootstrap/node.js:752:3)    

But Shard Size is 5432. I am not sure what is missing here and causing trouble, Please guide.
