Error: DotnetCliPackageBuilder:RunPackageAction - [WinError 267] The directory name is invalid

Describe the bug

CodeUri in Function has invalid directory name

To Reproduce

• Create a powershell package using the new-awsPowerShellLambdaPackage:

New-AWSPowerShellLambdaPackage -ScriptPath checkdomainavailable.ps1 -OutputPackage checkdomainavailable.zip

• Add the function in template.yaml

CheckDomainAvailableFunction: Type: AWS::Serverless::Function Properties: CodeUri: lambda/check-domain-available/checkdomainavailable.zip Handler: checkdomainavailable::checkdomainavailable.Bootstrap::ExecuteFunction Runtime: dotnetcore3.1 Role: !GetAtt OnBoardingR53LambdaRole.Arn Events: APIEvent: Type: Api Properties: Path: /checkdomainavailable Method: post RestApiId: !Ref OnBoardingAPI

• Use the AWS: Deploy SAM Application

Deployment will fail with the following output: An error occurred while deploying a SAM Application. Check the logs for more information by running the "View AWS Toolkit Logs" command from the Command Palette. Starting SAM Application deployment... Building SAM Application... Error with child process: Building function 'StartPaymentFunction' ,Running NodejsNpmBuilder:NpmPack ,Running NodejsNpmBuilder:CopyNpmrc ,Running NodejsNpmBuilder:CopySource ,Running NodejsNpmBuilder:NpmInstall ,Running NodejsNpmBuilder:CleanUpNpmrc ,Building function 'CheckDomainAvailableFunction' ,Running DotnetCliPackageBuilder:GlobalToolInstall , ,Tool 'amazon.lambda.tools' was reinstalled with the latest stable version (version '4.1.0'). ,Running DotnetCliPackageBuilder:RunPackageAction ,Error: DotnetCliPackageBuilder:RunPackageAction - [WinError 267] The directory name is invalid

Expected behavior

The function should be deployed to Lambda

Desktop (please complete the following information):

• OS: Windows_NT x64 10.0.18362
• Visual Studio Code Version: 1.49.2
• AWS Toolkit Version: 1.14.0

Additional context

In the template an additional nodejs function, as well as API and IAM roles are also deployed. This worked fine before I added the dotnetcore function.

Testing performed

I already tried moving the generated zip file to other directories anad different runtime dotnetcore2.1

Status

• This is a sam build issue.
  • sam deploy without sam build works.
• Toolkit could avoid this problem by skipping sam build when deploying a CodeUri: ...zip

Hi, sorry it took a while, but I tried a full test. If I use sam deploy from commandline everything works as expected, under all circumstances.

Full command: sam deploy --template-file template.yaml --stack-name sam-pstestfull --capabilities CAPABILITY_IAM CAPABILITY_NAMED_IAM --region eu-west-1 --s3-bucket s3bucketname --profile profilename

This is the relevant template.yaml:

  CheckDomainAvailableFunction: 
    Type: AWS::Serverless::Function 
    Properties:
      CodeUri: lambda/check-domain-available/checkdomainavailable.zip
      Handler: checkdomainavailable::checkdomainavailable.Bootstrap::ExecuteFunction
      Runtime: dotnetcore2.1
      Role: !GetAtt OnBoardingR53LambdaRole.Arn
      Events:
        APIEvent:
          Type: Api
          Properties:
            Path: /checkdomainavailable
            Method: post
            RestApiId: !Ref OnBoardingAPI

I already tried C:\AzureRepos\reponame\WebAppPS and C:\AzureRepos\reponame and both fail using vscode AWS Toolkit.
