Slash escape in path issue

Hi everyone!

I am using Swagger UI to test some API for a KNIME Server. The requests require me to enter the path.

as you can see my path contains a slash (and I have no way to generate a work around by chosing a path that doesn't have a slash)

The requested URL that is generated, is then ...

which is obviously not working

I read through a lot forums where people facing the same issue. 

I tried everything from encoding/decoding and inverse but nothing is working.

Is there something that I'm missing or is it just not possible to escpae slashes in paths?

Best wishes
