To resolve the issue of exporting charts as blank images from multiple
dashboards in Apache Superset version 4.0.1, you need to ensure that the charts
are fully loaded before initiating the export process. The provided code
snippet shows the `handleBulkChartExport` function, which handles the export of
charts.
Here is the relevant part of the code:
```tsx
const handleBulkChartExport = (chartsToExport: Chart[]) => {
const ids = chartsToExport.map(({ id }) => id);
handleResourceExport('chart', ids, () => {
setPreparingExport(false);
});
setPreparingExport(true);
};
```
To ensure that charts are fully loaded before exporting, you might need to
add a check to confirm that the charts are rendered and ready. This can be done
by verifying the loading state and ensuring that the charts are not in a
loading state before calling the `handleBulkChartExport` function.
Here is an example of how you might modify the function to include such a
check:
```tsx
const handleBulkChartExport = (chartsToExport: Chart[]) => {
if (loading) {
addDangerToast(t('Charts are still loading. Please wait until all
charts are fully loaded before exporting.'));
return;
}
const ids = chartsToExport.map(({ id }) => id);
handleResourceExport('chart', ids, () => {
setPreparingExport(false);
});
setPreparingExport(true);
};
```
This modification ensures that the export process is only initiated when the
charts are fully loaded, preventing the issue of exporting blank images
