Geoprocessing Service: output layer used as input layer

Question

I have two custom geoprocessing tools (made with model builder and python scripts) through ArcMap that hosted through ArcGIS Server. The first tool outputs four layers as Feature classes. I select one layer from the output on the web app and use it as an input for the next tool. In my model, I use copy features on the input polygon. When I try to run the tool on the web app I get an error that "No features were found for processing." How can I appropriately use the output through AGOL to run the second tool? Is there a specific format I need to use for the layer or some sharing setting I need to do? (All of this works locally on ArcMap.)

Without seeing the geoprocessing tools in question I can't provide any solid guidance.

However if your second tool takes the output of the first tool you could publish the output of the first tool as a feature service to AGOL and then use that as the input for your second tool.

Alternatively is it possible to combine the two tools into one service?
