Map::setNode(): Not allowing to place CONTENT_IGNORE while trying to replace "air" at (-66,25,102) (block (-5,1,6))

can somebody explain what this mean's ?
i try to create a tree with a experimental function,

so the trunk is placed without error...

minetest.env:add_node({x=pos.x,y=pos.y,z=pos.z},{type="node",name="default:fence_wood"})
minetest.env:add_node({x=pos.x,y=pos.y+1,z=pos.z},{type="node",name="default:fence_wood"})
minetest.env:add_node({x=pos.x,y=pos.y+2,z=pos.z},{type="node",name="default:fence_wood"})
minetest.env:add_node({x=pos.x,y=pos.y+3,z=pos.z},{type="node",name="default:fence_wood"})
minetest.env:add_node({x=pos.x+1,y=pos.y+3,z=pos.z},{type="node",name="deko:deko_birch_leaves"})

the first mistake comes where the leaves should be set, whats wrong ?

You're trying to replace air with an unknown block; define it, or fix the name.

...or the Chunk is not loaded

strange I have same issue with tv mod (from jordach) ...
but all tv nodes exist and are registered ..
and it does the error with block loaded (be close to the tv node)
... I ask myself if this error occurs if we try to change a node with the same node ....
add node tv:screen_5 on at location of a tv:screen_5 node ..
Stupid ?

Hi, I had the same problem but I made a lot of try and I found it. http://minetest.net/forum/viewtopic.php?pid=29758#p29758

thx for the help,
its like Calinou said, i wrote the block defenition wrong, missed a letter, realy need new glases, cause i did not see that a long time

Ye the game may tell us which block it is trying to place.

if youre using abm's make sure they're not acting on unloaded chunks



or use
