Issue with Reframe work InitAllSettings workflow

Hello all.

I am getting this error System exception at initialization: Value cannot be null. (Parameter ‘source’) at Source: System.Linq in reframe work. while invoking InitAllSettings workflow in production.
It runs in my local machine without any errors.


  • check the input arguments of this invoke workflow. Are you passing anything that is not initialized?
  • do all you assets exist?
  • Are you connected to a proper orchestrator, and to the right folder?
  • Did any chickens cross the road, and if so, why?

Knowing that init all settings also starts with a logmessage which is not logged, my guess would be the input values you try to pass as arguments.

Add this log message and check dtSettings.Rows.Count whether the config file values are read or not

Check the arguments you are passing are configured correctly.

Previously for the in_Configsheets it was just {“Settings”,“Constants”}
Now I updated them as New List(Of String) From {“Settings”, “Constants”}.ToArray()
And enabled the isolated on.

Waing for the admin team to add the new package in orchestrator.

System.String[] is not a List(Of String) but an array of string. So the notation {"Settings","Constants"} is a correct notation for a static array.
I’d sooner suspect that your variable Config_Path is null.

I am passing it through a variable.
