failure on a Boolean point. 'Unable to convert status value to lonPrimitive'.
Ran into this issue on a site upgraded to 3.8.111 with a LON RIB relay
To command the relay on, you have to write to a snvt switch (nviValue) which has two elements, value (numeric) and state (enum). The state element had been added to the database as a Boolean writable point, and something changed in the Lon works module that no longer accepts this. I had to change the state point to an EnumWritable to make it follow the command.
