when cursor.get_blueprint_entities()

You can't run splitter specific methods

e.splitter_filter.name
e.splitter_input_priority
e.splitter_output_priority

error:
attempt to index field 'splitter_filter' (a nil value)

e.type is also nil (at least for splitters.)

error:
attempt to concatenate field 'type' (a nil value)

The fields are called

• filter
• input_priority
• output_priority

As documented, get_blueprint_entities() does not return a LuaEntity, so you cannot expect the returned objects to function like LuaEntities: https://lua-api.factorio.com/latest/Lua ... t_entities

You can use https://wiki.factorio.com/Blueprint_str ... ity_object as a reference for the "blueprint entity" that is returned by the function.

The whole API is sprayed with slight naming inconsistencies like that. I think "expecting" things to be different is actually quite possible especially for new modders :p.

@OP: Don't be discouraged. This happens to all of us. The next time just print the table and read what it actually says.
