In workflow manager server, step type "Add Comment",
we need to know what is a max length of User Prompt?
In fact, in the step properties, for User Prompt, we use an Arcade expression.
jobOutputValue($job, STEP_ID, 'message')
But at a runtime, when a length of 'message' is more than some value, User Prompt contains not an actual text but the Arcade expression we put to the step properties.
