Hi quick question, I am just getting started and have run the following commands listed in the docs •

npx create-serverless-stack@latest my-sst-app --language python

•

npm run test

I get the following error:

Cannot find a handler file at src/lambda.js".

Is it possible to change the default extension sst looks for to .py? instead of .js?

Is the error on the test command?

It might be that the test command isn’t running the Python files.

Jay

What’s the extension of the file in the src directory?

Ah its because the default code generated doesnt include the

runtime: "python3.7"

configuration when the API is defined. However, it does seem a bit weird because the default function props are already set in index.ts

app.setDefaultFunctionProps({

runtime: "python3.7"

});

Hmm that’s weird. @Frank can you take a look at this?

Yup, taking a look.

Hey @Hosy Mia, in your

test/MyStack.test.js

, replace

Copy code

const app = new <http://sst.App|sst.App>();

with

Copy code

const app = new <http://sst.App|sst.App>();
  app.setDefaultFunctionProps({
    runtime: "python3.7"
  });

Each test creates a new

<http://sst.App|sst.App>

object in this case.

Just opened an issue for this https://github.com/serverless-stack/serverless-stack/issues/534

Hey @Hosy Mia, we just release v0.32.1 with a change to the

create-serverless-stack

Python template to set the default function props in the test, similar to the code snippet above.
