Question

CLI serverless function deployment and running issue

Hello community 👋

I’m new to the DO and right now interested particularly in scheduled functions to automate my processes.

Using this documentation https://docs.digitalocean.com/products/functions/how-to/create-functions/ I created serverless function within typescript template.

My main issue While I was working within 1 file function by testing different triggers and deployments - everything was fine. When I add additional folders and helper functions - it stops running.

Hi there,

I think that you are missing a build.sh file in your lib directory.

The contents of the lib folder and the contents of each function’s directory affect what is included in each deployed function and how that function is built.

Here is also an example project that might help:

https://github.com/digitalocean/sample-functions-todo/tree/main

The structure is more or less just the build.sh file and your library.

Here is also another example on how this is implemented:

https://github.com/digitalocean/functions-deployer/tree/main/e2e/use-lib/lib

The above is from an end-to-end test and includes a simple use of the lib directory and a build.sh file.

If your serverless function repository is public, feel free to share it here and I will be happy to take a further look at why the builds might be failing.

Here is also a link to the official documentation on how the build sequence works:

https://docs.digitalocean.com/products/functions/reference/build-process/#the-build-sequence

Let me know how it goes!

- Bobby
