When you see an error that 'choiceLabels and choiceValues array must be the same length', what is the most likely issue?

• A. the choiceLabels have to be longer
• B. the component's data source is invalid
• C. the choiceLabels and choiceValues arrays must be in the same order
• D. the choiceValues has too few values

Answer: (D)

In this scenario, the mapping between the two arrays is what matters. When you show a list of options, each label must have a corresponding value at the same position in the both arrays. That means the two arrays must be the same length. If one array is shorter, some labels won’t have a matching value, triggering the error about the arrays needing to be the same length. The message you’re seeing often comes from having fewer items in the choiceValues array than in the choiceLabels array. For example, three labels with only two values means the third label has no value to pair with. The fix is to ensure both arrays have the exact same number of items, so every label has a corresponding value. If you’re building these arrays dynamically, double-check the logic that constructs them to guarantee equal lengths. Also remember that having extra items in the values array without matching labels would cause the same issue in the other direction.
