azure devops doing overwriting issue with reactjs

[bilalmalik777]

I create a build pipeline in Azure DevOps for reactjs, it builds the code into somerandomNumber.zip. Under zip file, there is a build folder in which all publish code exists. In iis web app manages the task in release, the physical path is given following %SystemDrive%\inetpub\wwwroot\build. it deploys the code in wwwroot/build/build, actually it must deploy into wwwroot/build/ not in wwwroot/build/build. owing to which everytime i have to copy code from the innermost build folder to the outer build folder. please help me to sort out this problem. Build and release configuration are given below
