// V40 normalizes the dashboard refresh property to ensure consistent string typing.
|
|
//
|
|
// This migration addresses type inconsistencies in dashboard refresh configuration that could
|
|
// cause runtime errors or unexpected behavior. Over time, the refresh property has accumulated
|
|
// various data types (boolean, numeric, null, undefined) due to different dashboard creation
|
|
// methods, API usage patterns, and legacy imports.
|
|
//
|
|
// The migration works by:
|
|
// 1. Checking if the refresh property exists and is already a string type
|
|
// 2. Converting any non-string values (boolean true/false, numbers, null) to an empty string
|
|
// 3. Ensuring all dashboards have a consistent string-typed refresh property
|
|
//
|
|
// This normalization is critical because:
|
|
// - The frontend refresh logic expects string values for parsing time intervals
|
|
// - Non-string values can cause dashboard loading failures
|
|
// - Empty string is the standard representation for "no auto-refresh"
|
|
// - Consistent typing enables proper validation and UI behavior
|
|
//
|
|
// Example transformations:
|
|
//
|
|
// Before migration:
|
|
//
|
|
// refresh: true // boolean
|
|
// refresh: 30 // number (seconds)
|
|
// refresh: null // null value
|
|
// refresh: undefined // missing property
|
|
//
|
|
// After migration:
|
|
//
|
|
// refresh: "" // normalized to empty string
|
|
// refresh: "" // normalized to empty string
|
|
// refresh: "" // normalized to empty string
|
|
// refresh: "" // property added with empty string
