Hello I could always send an array (6) with real to my S7 1200 with node red and node-red-contrib-s7 V2.3. After update to node-red-contrib-s7 V3.0 this no longer works, I always get an error (see picture). I have not changed anything, besides updatring node-red-contrib-s7 V2.3 to V3.0

Array_Error

For reading arrays to work correctly, you need to declare two square brackets, for example

[[1,2,3,4]]

because there is the possibility of writing more than one array at once, that is, an array of arrays, for example

[[2,2,2,2,2],[4,4,4,4]]
