Infinity error - The Expand Must Be An Array

I'm getting an error when I "get item" from Infinity - "the expand must be an array". Can you tell me what the error means, and how I could fix it?

I have asked Infinity, but they have directed me to Pabbly.

Here is the workflow results, with the error:

Here is the workflow settings for Get Item (I get the Item ID from the Search step before):

Hey @wibbler

Name the workflow in which you have noticed the error?

"3. Create Job Sheet"

Hey @wibbler

If you can see retrace the history log of your workflow, your items are not coming from the above action or trigger response in the "Get Items" action step and also noticed that you have changed the trigger event to Email Parser now.

So, kindly make sure you are getting the Item id in the execution correctly which is required to Get the Item action.

Ok thank you! Look like it is working.
