Try offsetting the sketch to ensure that it is in the part. Make the bottom of the sketch against the base plate be inside that plate. Also, try out the feature script rib feature! https://cad.onshape.com/documents/57363e63e4b0b9290a2ccf9f/v/1f9ee286dca055776bd790a3/e/c329a190efc2812bab1232c4

Ya, the edges of your sketch which touch your existing geometry need to be drawn such that they are inside of the part. As it is shown, your rib will be tangent to the outside of your model, and that will not work.
