Getting System.IO.DirectoryNotFoundException:

[enteringAusernameAgain]

This is where I get the error:
await memo.ImportDocumentAsync(path, steps: Microsoft.KernelMemory.Constants.PipelineWithSummary);

The code includes:
string modelsPath = @"C:\rahul\Meta-Llama-3-8B-Instruct.Q2_K.gguf";
LLama.Common.InferenceParams infParams = new() { AntiPrompts = ["\n\n"] };
LLamaSharpConfig lsConfig = new(modelsPath) { DefaultInferenceParams = infParams };
SearchClientConfig searchClientConfig = new()
{
MaxMatchesCount = 1,
AnswerTokens = 100,
};

       TextPartitioningOptions parseOptions = new()
       {
           MaxTokensPerParagraph = 300,
           MaxTokensPerLine = 100,
           OverlappingTokens = 30
       };

IKernelMemory memo = new KernelMemoryBuilder()
.WithLLamaSharpDefaults(lsConfig)
.WithSearchClientConfig(searchClientConfig)
.With(parseOptions)
.Build();

I am using:
using LLama.Common;
using LLama;
using LLamaSharp.KernelMemory;
using Microsoft.KernelMemory.Configuration;
using Microsoft.KernelMemory;

Tried fixing file naming and directories and I also tried the below, but it gives the same error:
await memo.ImportWebPageAsync("https://cdsarc.u-strasbg.fr/ftp/cats/J/A+A/ReadMe.txt", step...
