Cannot publish DotNet 5 app with blazor webassembly to Lambda

[genifycom]

Describe the bug

When trying to publish a DotNet 5 webassembly app to Lambda for Visual Studio 16.9.4 using the AWS Toolkit 1.21.0.0, I get the following error

... publish: C:\Program Files\dotnet\sdk\5.0.202\Sdks\Microsoft.NET.Sdk.BlazorWebAssembly\targets\Microsoft.NET.Sdk.BlazorWebAssembly.Current.targets(617,5): error MSB4096: The item "C:\Dev\Projects\AWSBlazor\AWSBlazor\Client\bin\Release\net5.0\AWSBlazor.Client.runtimeconfig.json" in item list "AllPublishItemsFullPathWithTargetPath" does not define a value for metadata "RelativePath". In order to use this metadata, either qualify it by specifying %(AllPublishItemsFullPathWithTargetPath.RelativePath), or ensure that all items in this list define a value for this metadata. [C:\Dev\Projects\AWSBlazor\AWSBlazor\Client\AWSBlazor.Client.csproj]

To Reproduce

Create a DotNet 5 Blazor Webassembly app with host included. Replace the Server with an AWS Lambda Serverless app and try to publish to lambda. Project included for reference. AWSBlazor.zip

Expected behavior

This project does run locally, but I am unable to publish to Lambda using the AWS Toolkit.

Screenshots

Desktop (please complete the following information):

• OS:
• Visual Studio Code Version: 16.9.4
• AWS Toolkit Version: 1.21.0.0

Just tried this again with the AWS Toolkit 1.21.1.0 with the same result.

... publish: C:\Program Files\dotnet\sdk\5.0.202\Sdks\Microsoft.NET.Sdk.BlazorWebAssembly\targets\Microsoft.NET.Sdk.BlazorWebAssembly.Current.targets(617,5): error MSB4096: The item "C:\Dev\Projects\AWSBlazor\AWSBlazor\Client\bin\Release\net5.0\AWSBlazor.Client.runtimeconfig.json" in item list "AllPublishItemsFullPathWithTargetPath" does not define a value for metadata "RelativePath".

Hi @genifycom

Are there any other logs, and are you able to deploy this via a sam deploy command? The logs should show the exact commands we're running, but for the most part, we're running a sam build to a temp directory, a sam package to an S3 bucket, and following up with a sam deploy.

Hi there. This is using the AWS Toolkit in Visual Studio "Publish to AWS Lambda..."

As such, it is using Docker (DotNet 5) and dotnet publish.

The build log follows:

Oh, I think you might have the wrong extension (this is the VS Code extension, not the Visual Studio one). I'll go ahead and transfer this to that repo.

Ah, sorry about that. Thank you
