Minimum Bounding Volume Tool Error in Model Builder ArcGIS Pro 2.5

[Anonymous User]

I am attempting to create Minimum Bounding Volumes from clipped point features that have Z values, but the Minimum Bounding Volume Tool will not accept any 'modified' point feature as input in Model Builder (ArcGIS Pro 2.5) until I run the tool and generate the clipped points first. Of course this defeats the purpose of the model, as I wanted to publish this as a geoprocessing service in a Web App. 

I get this error:  00241: The specified pathname or file type is invalid for the required input. My points are derived from a Multipoint feature.  I spoke with an ESRI expert about this at length and tried multiple avenues and they believe this is a bug, after observing my model's behavior.  Again, Minimum Bounding Volume will accept PilePts as input after they are created, but not otherwise.

I can input the unmodified point features no problem, without clipping, as shown below.  So I do not believe this is a data type issue.  But I don't see where I would put a precondition in either.  I am not using any additional parameters in the MBV Tool, so this should be simple.  My pathnames are fine (the Output Name variable is there, just not visible in the image). I have tried this in a folder and a file geodatabase.

Has anyone experienced this same issue with this or another tool?.

Can you cheat it by using an Environment Variable (Processing Extent) on Points_with_Z, and have it as a parameter?

Of course THANK YOU!  I have been so focused on stringing other models together, I didn't even think of setting an extent.  Such an obvious workaround.  Now the trick is to see if this works with a Feature Set in a Geoprocessing Service...
