Candidate search: Cannot read properties of undefined

[adnjerem]

There is an issue with the search function of the CDR editor, where sometimes an error gets displayed in the top bar, for example:

TypeError: Cannot read properties of undefined (reading 'TotalCount')

TypeError: Cannot read properties of undefined (reading 'Hierarchy')

We found the error in a custom portal where we use the CDR editor, but it can also be reproduced in the IT-Shop.

There is a timing component to the issue, so it doesn't happen all the time. To reproduce it, start typing in a field (in the screen shot below: "h"), then make a short pause such that the browser sends a search request to the backend, then immediately resume typing before the response arrives (in the screenshot below: "ans"). This cancels the first request and triggers a new one, and the error appears.

I found the following snippet in qbm/.../cdr/edit-fk/edit-fk.components.ts in the updateCandidates function:

const candidateCollection = await this.selectedTable.Get(this.parameters);
this.candidatesTotalCount = candidateCollection?.TotalCount;
 
this.isHierarchical = candidateCollection.Hierarchy != null;

It could explain the error message in our custom portal, where the error indicates reading Hierarchy, but not the one from the IT-Shop where it reads TotalCount and the code correctly uses the null-safe navigation operator.

I can confirm this (bad) behavior with cancelling search requests by resuming input in search-input-field (9.2.0 with codebase from commit #146 ).
Would be great to have a fix for that!

Great catch - creating a bug for tracking
