Block.Reference.Create operation failed

I’m trying to create blocks using the Block.Reference.Create command, where I have a tree block and using the coordinates extracted from a corridor feature line.

However, when executing the code, the following message appears:
Warning: BlockReference.Create operation failed.
eInvalidInput

Can anybody help me?

Try using the BlockReference.ByCoordinateSystem node instead of BlockReference.Create. Then plug in the coordinate system node you have on the far left of the image in your post.

ByCoordinateSystem

Thanks for the tip!
I used the 'Block Reference.ByCoordinateSystem node and the problem in Dynamo remained, however the blocks were created in civil 3d and I had not seen it.
