    Hi Alicia,

    It looks like this error is coming from a typo in the command that you ran. The tool is providing this error: A USER ERROR has occurred: Illegal argument value: Positional arguments were provided ', }' but no positional argument is defined for this tool. This indicates that the tool isn't reading your command properly. Could you check to ensure that there are no additional or missing spaces in your command, etc.? Here is a similar post with the same issue.

    Kind regards,

    Pamela
