sam init: "Error: Multiple lambda image application templates found"

[justinmk3]

This started happening in our CI today. Maybe caused by 27dce06 ?

$ sam init --name testProject --no-interactive --dependency-manager pip --package-type Image --base-image amazon/python3.8-base

Cloning app templates from https://github.com/aws/aws-sam-cli-app-templates
Error: Multiple lambda image application templates found. This should not be possible, please raise an issue.

Note the above command uses python3.8-base ; this does not happen with e.g. python3.7-base :

$ sam init --name testProject --no-interactive --dependency-manager pip --package-type Image --base-image amazon/python3.7-base

Just experienced the same issue when trying to select python3.8

For reference: cannot use --app-template to workaround this, because sam does not allow it with --base-image:

Error:
You must not provide both the --base-image and --app-template parameters.

from aws/aws-sam-cli#2846 (comment) :

The issue is fixed in V.1.24.0
you can now use the --app-template argument to resolve this. For example:

sam init --name foo --package-type Image --base-image amazon/python3.8-base --app-template hello-world-lambda-im

This has been fixed in 1.24 of SAM CLI. Closing.
