I cannot find the Object Type for a Bevel Object.
I can find other deformers like "Obend - Bend deformer", but I do not see the Bevel.
Hi Pim, thanks for spotting it!
For the time being, until it won't be publicly exposed, you can use the value 431000028.
Just a side note that it's always worth repeating, you can drag and drop the parameters label in the Python Console to gain knowledge about the ID used to store their value - if present - in the object's BaseContainer.
And yes, I used that value already.
