Notarization of an simple project is was not working

We are developing an application for MAC machine using .NET. After developing and signing the package in notarization process was failed with the error in the attached file.

Then we have created the simple Xamarin.MAC to check whether able to notarize it . But with the simple project also we have faced the same error.

We have tried to codesiginin the app to resolve the notarization error, but while code signing the below error was thrown

"unable to build chain to self-signed root for signer "Developer ID Application" (not mentioning the certificate id) SFSecure.app: errSecInternalComponent"
