Delete last / from a mappath

[Joppel]

Hello Experts,

I have two document libraries. Between these libraries I copy files which are edited by employees. After editing, these files must be copied back to the original location. The location where it should be copied back to is given to the original file as metadata. This is the folderpath where the original file is located.
for instance :
/projects/742-bb/

The problem is the last "/"

Is there a way to remove that last "/" from the path?

Hi @Joppel 

Here it is

Above expression is as follows:

substring(outputs('Compose'),0,sub(length(outputs('Compose')),1))

Thanks
