Boolean operation would result in non-manifold body

Hello :). I'm trying to make a boolean out of these two parts

However, I get the error message: "Boolean did not regenerate properly. Boolean operation would result in non-manifold body", with the erorr happening particularly on this line:

This is what I see when I zoom up close, on the edge:
