I am trying to pass value from a visualforce page to a flow using
.
Document:https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_flows_setting_values.htm
However when referencing field values from the Account in my flow I get an error saying: The flow failed to access the value for Account.customfield__c because it hasn't been set or assigned.
My question is what all fields are passed from the visualforce page to the flow.
Do I need to define the individual fields in my flow under 'Assign the records's fields to variables to reference them in your flow' before using them.
