IronPDF in AWS Lambda .NET 8: Missing Chromium Binary Errors

When running IronPDF inside an AWS Lambda .NET 8 container image, the application fails with an exception indicating that the embedded Chromium binary cannot be found.

IronSoftware.Exceptions.IronSoftwareEmbeddedDeploymentMissingException:
Failed to find embedded resource 'Chrome.linux-x64.zip'

The full exception stack may appear as:

Unhandled exception. System.Exception: Error while convert DOCX document to HTML:
IronSoftware.Exceptions.IronSoftwareEmbeddedDeploymentMissingException: Failed to find embedded resource 'Chrome.linux-x64.zip'
   at IronSoftware.Deployment.AssetManager.GetEmbededResourceStream(...)
   at IronSoftware.Deployment.EmbeddedResourceDeployment.Deploy()
   at IronPdf.Engines.Chrome.LocalChromeClient.Initialize()

Three conditions cause this error. First, if the AWS Lambda Mock Test Tool runs the function on Windows while the Dockerfile targets Linux, the embedded resource platform does not match the runtime. Second, IronPdf.Slim is a Linux-only package and fails when the runtime is Windows. Third, the container base image may not satisfy IronPDF's platform requirements.
