FAQ: How do I escape curly braces to distinguish between a GraphQL query and a handlebars expression?

To distinguish between a GraphQL query with one set of curly braces {...} and a handlebars expression with two sets of curly braces {{...}}, use double quotes (" ") around the handlebars expression and the braces. This is especially required if the handlebars expression will populate a string. Proper formatting in your handlebars expression will help distinguish as well. For example, rather than:

{"target":{"UserId":{{record.customerId}}}}

use

{
 "Target":
  {
   "UserId":{{record.customerId}}
  }
}
