Fix bytes in encode method args not properly handled

[sidt-cb]

Motivation

Fixes bytes not being properly encoded in method args (see test)

Solution

Currently doesn't work because it creates an empty slice and then copies onto it, but since slice was empty it was not able to receive copied bytes. Updated to create a slice with correct length to hold all decoded bytes
