While running scenarios file with daml script command against in memory snadbox, it is throwing Invalid Party arguments as parties are already allocated with first script

I was trying to run 2 script with daml script command then execution of second script is failing with error Parties arguments are invalid as it is already assigned.

Attaching the 2 script file that I am running one after the another.

daml script --dar .\.daml\dist\quickstart-0.0.1.dar --script-name Main:initialize --ledger-host localhost --ledger-port 6865

daml script --dar .\.daml\dist\quickstart-0.0.1.dar --script-name Main1:initialize --ledger-host localhost --ledger-port 6865

As I am new to Daml so I am not allowed to attach the script files so pasting content of the script file here -

  submit bob do exerciseCmd iouTransferBobCid IouTransfer_Accept

Note : I have tried removing allocate party logic from second script file that runs later but then compilation is complaining

I figured out the issue from another discussion where Parties to be passed with --input-file if any script has already allocated the parties… More detail information can be found on https://docs.daml.com/daml-script/index.html?_ga=2.90836954.1389845661.1605168012-1584537048.1598874835

Welcome to the forum Abhishek! Pasting code is fine and the preferred method of sharing on the forum.
