DeployClient Unable to overwrite existing file

Hi There, Im modifying our Azure Dev Ops release pipeline to deploy modules onto the Staging slot (with the Poly Deploy task) , then do an azure Slot Swap , then Deploy again (with Poly Deploy) to the Prod slot - so that there is no downtime.

However, on the second deployment the Poly Deploy task fails with this error :

##[error]Unhandled: Failed cp: cp: dest file already exists: D:\a\1\s\ModuleName_Install.zip

Here's some additional logging if it helps.

C:\hostedtoolcache\windows\DeployClient.exe\0.9.3\x64\DeployClient.exe --target-uri https://website.net --api-key 123 --encryption-key xyz --no-prompt --installation-status-timeout 60
