write FCStd node

[macdroid53]

I am trying to use the write Fcstd node.

g
When an update is triggered I get the following message:
File "/home/mac/.config/blender/3.6/scripts/addons/sverchok-master/nodes/exchange/FCStd_write.py", line 155, in fc_write_parts F.setActiveDocument(Fname) RuntimeError: Try to activate unknown document 'Hand-1'
The file FCStd file does exist.
If the file doesn't exist, it throws the same message, but, does create the file. But there is no data in the file.

Have I got something wrong? What don't I get?

With more experimentation, it appears the "Mesh to solid" and "Get objects data" don't update until the selected mesh object is in edit mode. Then the "write FCStd" node update button needs to be clicked.

But, should I need to intervene? Live update is set.
