Issue 種別: bug
難度: 3
推定時間: 1-3 hours
活動状況: stale
明確さ: clear
前提条件: Basic knowledge of Keystone field typesFamiliarity with React admin UI
初心者向け度: 60
調査方針: Investigate the TextArray field component and the Select field component in the Keystone admin UI. The error 'nextProps.value.join is not a function' suggests that nextProps.value is not an array. Check how the value is passed from the Select field to the TextArray field. Also, examine the dependsOn logic to ensure the TextArray field appears when dependency is met. Relevant files are likely in the fields directory, such as 'fields/types/TextArray.js' and 'fields/types/Select.js'.
