| That expression returns, e.g.: `{ field: [ red, green ] }` and `{ field: [ apple, lime ] }`, but not `{ field: fruit }` or `{ field: [ orange, lemon, grapefruit ] }`. |
There was a problem hiding this comment.
Quotes around "field" and string values, so { "field": ["red", "green"] }. We should use valid JSON where possible for consistency and so code samples are easier to copy/paste.
