Nuget generation by console

I'm trying to generate nuget packages by command, but it gives me an error. I put you in situation.

I have generated the .nuspec file with the command

nuget spec

The file structure is as follows

<?xml version="1.0"?>
<package >
  <metadata>
    <id>$id$</id>
    <version>$version$</version>
    <title>$title$</title>
    <authors>$author$</authors>
    <owners>$author$</owners>
    <licenseUrl>http://LICENSE_URL_HERE_OR_DELETE_THIS_LINE</licenseUrl>
    <projectUrl>http://PROJECT_URL_HERE_OR_DELETE_THIS_LINE</projectUrl>
    <iconUrl>http://ICON_URL_HERE_OR_DELETE_THIS_LINE</iconUrl>
    <requireLicenseAcceptance>false</requireLicenseAcceptance>
    <description>$description$</description>
    <releaseNotes>Summary of changes made in this release of the package.</releaseNotes>
    <copyright>Copyright 2019</copyright>
    <tags>Tag1 Tag2</tags>
  </metadata>
</package>

Now I would like to generate it based on the dynamic tags ($id$), for that, I use the following command.

nuget pack "nompre.proyecto.csproj" -Version 6.6.6 -Properties Configuration=release;Id="MiPaquete.Sample";Description="MyDescription";Authors="MeMeMeMeToo";Summary="MySummary";ReleaseNotes="MyChanges";Owners="MyCompany";

It throws me the following errors

Authors is required .

Description is required .

The truth is that I do not understand why, since the labels are there and the command, from what I have seen, it is separated by semicolons.

The idea is to be able to make the entire .nuspec dynamic, with labels, images for each nuget, etc.
