Description
What were you initially searching for in the docs?
Current layout to in the docs for routes across multiple files is not working.
- Tests out of the box on Pycharm does not work when you select a test to run
- Running the lambda products an error too
Is this related to an existing part of the documentation? Please share a link
- Sample Layout is not working.
If you have a proposed update, please share it here
- ✔️ Here is the working version tests and deployed - https://github.com/michaelbrewer/demo-multi-file-router/tree/working
- ✔️ Another example which works for http api - https://github.com/michaelbrewer/demo-multi-file-router/tree/working-http-api
- 🐛 Here is the one based on the docs, which does not work - https://github.com/michaelbrewer/demo-multi-file-router/tree/not-working
