My speculation is that this is an order of creation problem.
That is, you are creating and writing to the variable before
you attempt to set the _FillValue attribute.
You might try to rewrite your code to make sure that the
order of events is as follows:
1. create variable (but do not write to it)
2. add _FillValue attribute
3. write data to the variable.
