I try to wrap an R based application that is deployed to a docker container. I changed the base image to lambda/python3.9 and added another app with its own Dockerfile. This contains a simple python script as the handler for the function. In this handler I call the code to run the R script and upload the result to S3. Now when I'm testing locally everything works fine. But when I push the image to ECR and deploy the container as a Lambda Function I get following error:
{
"errorMessage": "Unable to import module 'app': No module named 'app'",
"errorType": "Runtime.ImportModuleError",
"requestId": "1a7fa818-62e4-4374-8318-625b15e2ae8a",
"stackTrace": []
}
