The documentation for AWS Lambda functions (using the AWS Classic provider) lists the

provided.al2023

runtime as supported. See here: https://www.pulumi.com/registry/packages/aws/api-docs/lambda/function/ (scroll to the very bottom). However, using that runtime results in the following error:

Diagnostics:
  aws:lambda:Function (<our-function-name>):
    error: aws:lambda/function:Function resource '<our-function-name>' has a problem: expected runtime to be one of [nodejs nodejs4.3 nodejs6.10 nodejs8.10 nodejs10.x nodejs12.x nodejs14.x nodejs16.x java8 java8.al2 java11 python2.7 python3.6 python3.7 python3.8 python3.9 dotnetcore1.0 dotnetcore2.0 dotnetcore2.1 dotnetcore3.1 dotnet6 nodejs4.3-edge go1.x ruby2.5 ruby2.7 provided provided.al2 nodejs18.x python3.10 java17], got provided.al2023. Examine values at '<our-function-name>.runtime'.

I'm up-to-date with the CLI and the plugins, see:

❯ pulumi version
v3.114.0
❯ pulumi plugin ls
NAME        KIND      VERSION  SIZE    INSTALLED      LAST USED
aws         resource  5.43.0   547 MB  7 minutes ago  7 minutes ago
aws-native  resource  0.103.0  98 MB   8 minutes ago  7 minutes ago

I can work with

provided.al2

for now, but I'd really like to upgrade to

provided.al2023

. Is this behaviour a bug or did I do something wrong?

provided.al2023

should definitely be a supported value. The version of the

aws

plugin you're using is a bit old (current is 6.33.0) so I imagine you'd just need to update.

Ah, indeed. I was under the impression that I was running the latest version of the plugins because I had run

pulumi plugin rm --all && pulumi up

. The major version change I did not take into account. Thanks for your reply cute pulumi heart
