Error when Adding a product

[kserrano]

I recently install the OM plugin in my developer environment, configure a product but somehow I am getting this error when I added the product.
Any idea how to fix this? I have tried to repair the plug, reinstall. but still getting this.

aside from the this plugin, do I need to install anything else? I have added but the workspace is not showing. did I miss anything?
