"Duplicate Objects along Edge" node turns red when setting the scaling to "none"

Problem statement

"Duplicate Objects along Edge" node turns red when setting the scaling to "none".

Steps to reproduce

I am still trying to make train tracks and currently trying out the "Duplicate Objects along Edge" node. Everything works fine, except that the duplicated meshes get malformed.

You can see the original grey box in the middle and the distorted clones in blue around it. I tried to change the scaling mode to off, however this just errors out the node. https://ibb.co/pwt4768

Expected result

Exact copies of the source mesh distributed along the curve. (They should rotate around their z axis, according to the curve, however.)
