invalid blank Outside Boundary Condition Object

Hi everybody, I face with an error in OpenStudio and I would appreciate if you help meto solve it. I saw that many people got the same error linked to the surfaces and subsurface, I read the tips, but I could not solve mine. When I run the model I get the below error. "Severe * FenestrationSurface:Detailed="FACE 4", invalid blank Outside Boundary Condition Object * ~~~ ** ...when Base surface uses "Surface" as Outside Boundary Condition Object, subsurfaces must also specify specific surfaces in the adjacent zone." I get the same error for the other doors, subsurfaces Thanks in advance for your help!!image description

Can you post an example of one of these problematic OS:SubSurface definitions in your .osm file (CTRL-F in a text editor)? For a sub surface, one can leave blank its Outside Boundary Condition Object if its base surface faces the outdoors, for example. But for paired interzone base surfaces, 2x OS:SubSurfaces must also be paired, i.e. reference each other (each Outside Boundary Condition Object can't be left blank). OpenStudio will rely on setAdjacentSubSurface to accomplish this.

There is a bit more flexibility in native E+ as discussed here, but it looks like there's an error in the docs (there's no reason to reference an adjacent ceiling in there).
