I get response registryReportSettings from server:
this.getRegistrySettings(registry.Id).subscribe((registryReportSettings: { extended: ReportPropertiesRequest }) => {
const { objectProperties, reportProperties, textProperties } = registryReportSettings?.extended;
}
If it is null I get an error:
TypeError: Cannot destructure property 'objectProperties' of '(intermediate value)(intermediate value)(intermediate value)' as it is undefined.
How to fix it using TS?
The error means that you try to deconstruct a possible undefined (Because you use optional chaining)
You can do
const { objectProperties, reportProperties, textProperties } = registryReportSettings?.extended ?? {};
So you will always deconstruct an object
