To map values from repeating controls and multi-select controls to to the Keywords field type, the value should be a template string that resolves to multiple values. The recommended approach is to create a template that results in a JSON array using the built-in separator 'json' i.e. {json|controlname}. This special separator resolves to JSON format. The same result can be accomplished by specifying the JSON format i.e. ["{","|controlname}"]. |
