I am getting below issue while deploying SmartPy contract in ghostnet.

HttpResponse: Http error response: (500)
        "msg":"Error while applying operation oo4FzTAmMBt4tZ7Hbz5HE2fgDw441umhgtHRcSgHT1R4pWt7DBS:\nError:\n  The operation oo4FzTAmMBt4tZ7Hbz5HE2fgDw441umhgtHRcSgHT1R4pWt7DBS cannot be added because the mempool already contains a conflicting operation that should not be replaced (e.g. an operation from the same manager with better fees).\n"

The current restriction only allows one manager operation per block per account. Try to wait for the previous operation to be included in a block before running a new one.

(If you are using an account whose private key is public, such as tz1VSUr8wwNhLAzempoch5d6hLRiTh8Cjcjb, this may happen frequently as many people use it.)
