CLI serverless function deployment and running issue

Hello community ๐Ÿ‘‹

Iโ€™m new to the DO and right now interested particularly in scheduled functions to automate my processes.

Using this documentation 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 file in your lib directory.

The contents of the lib folder and the contents of each functionโ€™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:

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

Here is also another example on how this is implemented:

The above is from an end-to-end test and includes a simple use of the lib directory and a 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:

Let me know how it goes!
