Connect-ExchangeOnline from AWS PowerShell lambda throws PSRemotingTransportException

I am trying to connect to exchange from AWS Powershell Lambda function. The script is working fine locally but throws below error when executed from AWS.

{
  "errorType": "PSRemotingTransportException",
  "errorMessage": "This parameter set requires WSMan, and no supported WSMan client library was found. WSMan is either not installed or unavailable for this system.",

    "errorType": "DllNotFoundException",
    "errorMessage": "Unable to load shared library 'libpsrpclient' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: liblibpsrpclient: cannot open shared object file: No such file or directory",

Hi @geekganesh,

Good morning.

Please refer the existing issues aws/aws-tools-for-powershell#203 and #332 for details about this error and possible resolution. This error is related to OpenSSL library. Let me know if these help.

Thanks,
Ashish

Hi @ashishdhingra

I have created a AWS openssl layer to the lambda function. openssl support is available to lambda but i am getting the same error. Do i need to have my own container?

PSWSMan rewrites shared object files when running Install-WSMan. I have not been able to get it to work with a zip. Since it takes ~1 min to connect to exchange online, I've decided to build a container image, https://github.com/nickadam/powershell-lambda, https://github.com/nickadam/exo-lambda. It's slow but it works.
