Cannot get related items with PnPjs search on workflow task content type

Question

I am working on SPFx Project and using PnPjs search. My requirement is to search for pending workflow task for that I have created result source at site collection level. Builder query as below

{searchTerms} ContentTypeId:0x0108* Path:{SiteCollection.URL} WorkflowOutcomeOWSTEXT:Pending

Now I am using SPFx to retrieve data. I cannot get related item of the task or related item id for the original item. Other than that I get all data. Let me know I am doing wrong or there is some issue pnpjs

My code as below (SPFx v2.0.6 and SharePoint Online/2019)

const getContentTypeData = async (rowLimit: number, sourceId: string, querytext: string, selectedProperties: string[]) => {
const appSearchSettings: ISearchQuery = {
RowLimit: rowLimit,
EnableInterleaving: true,
SourceId: sourceId,
TrimDuplicates: false,
Querytext: querytext,
SelectProperties: selectedProperties
}
const searchResults: SearchResults = await sp.search(appSearchSettings)
return searchResults
}
const selectedProperties = ['ListItemID', 'Path', 'Title', 'HitHighlightedSummary', 'LastModifiedTime', 'ParentLink', 'RelatedItems']
const rowLimit = 10
let queryText = AssignedTo:"${displayName}" // Passing current user displayName
getContentTypeData(rowLimit, searchSourceId.PendingTask, queryText, selectedProperties)
.then((r: SearchResults) => {
setPendingTask({ totalRows: r.TotalRows, primarySearchResults: r.PrimarySearchResults })
})
.catch(console.warn)

Hi @Milind Saraswala ,

I am able to reproduce this issue here, the 'RelatedItems' property always returns null.

Based on below docs, SelectProperties must be managed properties and their retrievable flag should be true.

'RelatedItems' has not been crawled, so we need to map it to a managed property.

Result:

Note: Please make sure the task really has related items and it may cost some time for crawling.
