PowerShell - How to package custom modules into a zip package for AWS Lamdba

I am trying to package a script I have as a Lambda function. The script loads some functions from some other ps1 files in the same folder. Currently use "." to include. When I try to use New-AWSPowerShellLambdaPackage -ProjectDirectory projectName -OutputPackage projectName.zip to package the script files, it keeps failing with error below.

     |              ~~~~~~~~~~
     | Error publishing PowerShell Lambda Function: -1 CALLSTACK: Command                        Arguments                                                                                                   Location -------

     | OutputPackage=projectName.zip}                                                       New-AWSPowerShellLambdaPackage.ps1: line 182 <ScriptBlock>                  {}
     | <No file>

Is this because I use "." to source the other ps1 files? Should I convert them into modules? Anyone can suggest any documentation for this? I can't seem to find any good source detailing how to package PowerShell lambda. All the examples I can find are for single ps1 file.

You need to have a proper .csproj file to be able to use -ProjectDirectory switch.

I typically use the following procedure:

  1. Generate project structure using New-AWSPowerShellLambdaPackage with -StagingDirectory switch:

    New-AWSPowerShellLambdaPackage -StagingDirectory projectName -ScriptPath .\projectName.ps1 -OutputPackage projectName.zip

  2. Modify projectName.csproj to include additional files. Following example adds additionalScript.ps1 and all files within SQL folder into the package:

    <ItemGroup>
    <Content Include="projectName.ps1">
        <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </Content>
    <Content Include="additionalScript.ps1">
        <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </Content>
    <Content Include="./SQL/**">
        <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </Content>
    <Content Include="./Modules/**">
        <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </Content>
</ItemGroup>
  3. Use New-AWSPowerShellLambdaPackage with -ProjectDirectory switch to build the package: 
    New-AWSPowerShellLambdaPackage -ProjectName projectName -OutputPackage projectName.zip
