Is the error message

run the CreatePacakge.bat file in \scripts and it is true that no pdb file is created during the build.

This is strange as the build is

dotnet pack TimeSeriesAnalysis.sln -c Release --include-symbols -p:NuGetBuild=True -p:SymbolPackageFormat=snupkg --include-source

and the TimeSeriesAnalyis.csproj file includes

true
