Configuring your process model start forms and user input task forms via an in-line expression has been deprecated. The Write an expression option will be removed from the Process Start Form tab and the Forms tab in a future release of Appian.

Instead of configuring a form via an expression, directly select an interface and map inputs to your process variables. For more information, see:

• Process Model Start Forms
• User Input Task
• Process Node Properties
• Enable Offline Actions and Tasks

Any start form or user input task that was previously configured as an expression will continue to work as expected.
