I am trying to create a live Quip App usign the trailhead instructions in "Quick Start: Quip Live Apps". I have node and npm compatible versions installed.

I am getting error while executing this line on Command Prompt
.\bin\quip-apps init “J1 quip app” $QeEAjACfHeh

This is the error - '.\bin\quip-apps' is not recognized as an internal or external command, operable program or batch file.

Has anybody come across how to fix this error ?

Hi all,

I received the following error message and am not sure how to resolve it. Any support is really appreciated!
 

• "System error: The list of results isn't the same size as the input list. Got: 0 , expected: 1. Contact Salesforce support."

I first received the error message when I activated a new process in process builder. I turned that process off for now while I did some research but just got it when using the Data Loader to update some contact records. 

Thank you!!
