Test Tool: Internal Server Error: FileNotFoundException: Could not load file or assembly #594

alexbaileymembr · 2020-03-06T18:47:46Z

It seems like I'm having an issue that I can't see others coming across. I've checked everything I can think of but no matter what I do, when the lambda test tool opens in the browser, it fails to load the functions list.

In the network tab I can see:

500 Error: http://localhost:5050/webtester-api/Tester/aws-lambda-tools-defaults.json
FileNotFoundException: Could not load file or assembly 'Amazon.Lambda.Serialization.Json, Version=1.0.0.0, Culture=neutral, PublicKeyToken=885c28607f98e604'. The system cannot find the file specified.

Has anyone come across this before or can point me in the right direction? There are no errors in the console from me running it and I'm not totally sure where it's going wrong.

Might be worth mentioning that I'm running this on Ubuntu.

normj · 2020-03-06T19:12:14Z

I'm working on a new version of this tool that is tied with the upcoming .NET Core 3.1 release but also still support .NET Core 2.1. I have been doing some rework to how the Lambda code is loaded. If I provided a link to a preview build would you be willing to try it out.

alexbaileymembr · 2020-03-06T19:20:11Z

@normj definitely if it's backwards compatible with 2.1 since I would ideally not want to rework all my functions just yet 😅

normj · 2020-03-06T19:23:12Z

Yeap, going forward there were be 2 separate tools one for 2.1 and one for 3.1 but they will share a lot of the same logic. Let me clean things up and then I'll add a link to the 2.1 version.

alexbaileymembr · 2020-03-06T19:24:05Z

Appreciated thank you

normj · 2020-03-07T00:41:27Z

Here is a link to a preview build of the upcoming version.

https://normj-packages.s3.us-west-2.amazonaws.com/Amazon.Lambda.TestTool-2.1.0.10.0-preview1.nupkg

To install it download the nupkg file. Then in the directory that you download the file to run the following command to update your existing version.

dotnet tool update -g amazon.lambda.testtool-2.1 --version 0.10.0-preview1 --add-source .

brandon-king-halo · 2020-03-10T14:50:30Z

We were having trouble with 0.9.5 not loading the netstandard20 version of the NuGet package Microsoft.AspNet.WebApi.Client. Updating to the 0.10.0 preview resolved our issue.

normj · 2020-03-10T17:25:03Z

@brandon-king-halo Thanks for letting me know that 0.10.0 preview fixes the issue!

alexbaileymembr · 2020-03-11T09:38:52Z

Apologies I've not had chance to test this yet. I should be able to look at it this week!

pcvonz · 2020-03-12T19:08:15Z

FYI If anyone has trouble installing the nupkg locally. Run:

dotnet tool uninstall -g amazon.lambda.testtool-2.1

And then run:

dotnet tool install -g amazon.lambda.testtool-2.1 --version 0.10.0-preview1 --add-source .

@normj
I still get the same exception with the preview release:

You mentioned you were doing this on Ubuntu. Have you tried the same solution on anything besides Ubuntu? Wondering if this is a platform specific issue.

JoelRoxell · 2020-04-15T19:39:27Z

Might be related, tried to run using 3.1 and respective Test Tool on ubuntu 19.10.

dotnet new lambda.EmptyFunction --name LinuxFunction

dotnet build

(Note that it runs "properly" if the assembly reference (LambdaSerializer) is removed, but obviously that's not a solution)

ericmilaneze · 2020-04-22T13:06:32Z

Any update on this?

I'm using Fedora 31 (so it's seems not to be a Ubuntu issue as @normj suposed) with amazon.lambda.testtool-3.1 (0.10.0) and I tried the same as @JoelRoxell:

dotnet new lambda.EmptyFunction --name LinuxFunction
dotnet restore
dotnet build
dotnet lambda-test-tool-3.1 --no-ui

This is what I get as a response:

=============================================

As @JoelRoxell mentioned, it doesn't happen if I comment the following line of code:
[assembly: LambdaSerializer(typeof(Amazon.Lambda.Serialization.SystemTextJson.LambdaJsonSerializer))]

... but it turns out I tried the same on a real project and it started to complain about the Serilog:

System.IO.FileNotFoundException: Could not load file or assembly 'Serilog, Version=2.0.0.0, Culture=neutral, PublicKeyToken=24c2f752a8e58a10'. The system cannot find the file specified.

Sounds like it's not finding any dependencies.

Does anyone have any idea what's happening here?

normj · 2020-04-23T21:44:24Z

@ericmilaneze Could you try and experiment for me and in your csproj file add the property CopyLocalLockFileAssemblies with a value of true and see if that changes your behavior?

Here is a full csproj file example.

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <GenerateRuntimeConfigurationFiles>true</GenerateRuntimeConfigurationFiles>
    <AWSProjectType>Lambda</AWSProjectType>
    <CopyLocalLockFileAssemblies>true</CopyLocalLockFileAssemblies>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Amazon.Lambda.Core" Version="1.1.0" />
    <PackageReference Include="Amazon.Lambda.Serialization.SystemTextJson" Version="1.0.0" />
    <PackageReference Include="System.Data.SqlClient" Version="4.8.1" />
  </ItemGroup>
</Project>

rozpuszczalny · 2020-04-27T13:15:53Z

@normj
I'm facing the same issue that @ericmilaneze is facing. Adding mentioned property solved the problem.
Thank you!

ericmilaneze · 2020-04-29T12:05:11Z

It works!

Thanks, @normj!

carlmiddleton · 2020-05-08T01:34:44Z

@normj we are having a similar issue and get exception 'System.IO.FileLoadException' however slightly different stack trace. We tried adding the property above however did not solve the issue. When deployed to AWS this works fine.

We are using the latest test tool for 2.1 but when we use a nuget package that is built for .NET Standard we get the following error:

System.IO.FileLoadException: Could not load file or assembly 'Internal.Integration.Amy, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. An operation is not legal in the current state. (Exception from HRESULT: 0x80131509)

at System.Runtime.Loader.AssemblyLoadContext.ResolveUsingLoad(AssemblyName assemblyName)
at System.Runtime.Loader.AssemblyLoadContext.Resolve(IntPtr gchManagedAssemblyLoadContext, AssemblyName assemblyName)

Any ideas?

judedaryl · 2020-05-22T10:45:15Z

 <CopyLocalLockFileAssemblies>true</CopyLocalLockFileAssemblies>

Adding this worked for me. Can we add this to the README temporarily?

cohenalmog · 2020-06-16T15:27:46Z

    <CopyLocalLockFileAssemblies>true</CopyLocalLockFileAssemblies>

this is the only thing that solved my issue

k3nnet · 2020-09-09T04:31:39Z

adding the above mentioned property solved the issue for me as well .

soccerboymalloy-patriot · 2021-03-02T05:30:06Z

I'm using version 0.11.1 with a .Net 5 container Lambda. The test tool works fine for me in Visual Studio, but the Rider instructions result in the following error:

Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly
'System.Runtime, Version=4.2.2.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'
or one of its dependencies. The system cannot find the file specified.

I have <CopyLocalLockFileAssemblies>true</CopyLocalLockFileAssemblies> in my .csproj

Any thoughts?

EDIT: It turns out I was still version 3.1 of the test tool instead of version 5. I've created #821 to request formal documentation surrounding .Net 5.
