I am trying to build a Flow to create records for contacts. I am going to create a button off of Accounts on the related list of Contacts. 
Step 2 is where I am having an issue

1.) I created a Get Records - which gets the ID of accounts. 
2.) I created a Screen: 
    I have a lookup field that I want to be defaulted to the parent.

I have the FieldAPIName as AccountID which is a Varialble I created that is stored from Step 1. 
Label : Entity Name
Object API Name : Account

When I run the program I get the following error: 
Looks like you don't have access to this field, or the object or field API name is not valid on this Lookup component. Contact your Salesforce admin for help.







 

Hello, I have Lightning turned on in my Test Sandbox. How do I know when they have access to Lightning? I know I can create a profile/permission set to give them Lightning but the documentation says that salesforce will give them access to Lightning on a rolling basis.
