Is the error you are talking about the broken wire coming out of the last Build Array function?

If so, try turning on the Concatenate Inputs option in the right click menu of that function.  Right now you are taking 2 2-D arrays and creating a 3-D array.

(I don't see the point of writing pictures out ot a file to immediately read that file back in again.)

yes the error is the broken wire,

i try turning.....but the error still 😞

Right click on the Build Array node (it is right before the broken wire).  Pick "Concatenate Inputs".  Now the broken wire will be fixed.
