Error The path argument must be of type string - Headless app

[Anil_Umachigi]

Hey Guys! 

@dr_venture 

This one is new tried both on mac and windows, i get the error 

Error: The "path" argument must be of type string. Received undefined. 

I get this when i'm trying to create simple headless app from the codelab --> https://developer.adobe.com/app-builder/docs/resources/cron-jobs/ 

This happens only when i addd the triggers and rules to the yaml. 

triggers:

everyMin:

feed: /whisk.system/alarms/interval

inputs:

minutes: 1

rules:

everyMinRule:

trigger: everyMin

action: generic

The build works fine without it. 

What could be the cause? Here's a screenshot and aio info

@dr_venture Would really appreciate your help here! Thank you

I can see your issue. 

that yaml config file is space sensitive 

your package is sourceConnectorDS

It has Actions, Triggers, and Rules

all three are TOP level package items so they need to be at the same indentation level

sourceConnectorDS

   actions:...

   rules:...

   triggers:...

Above you have rules and triggers as sub-properties of actions so it thinks they are action definitions. 

Does that make sense for you?

phew thank you! I had a feeling that is it. 

I blindly followed the codelab, which might have caused the issue. 

The indentation needs to be updated here --> https://developer.adobe.com/app-builder/docs/resources/cron-jobs/lesson2/

Indentation on the config files can be tricky to see.
