False positive "Illegal assignment from List<AggregateResult> to List<AggregateResult>"

[PawelWozniak]

Summary

I am getting the false positive error message "Illegal assignment from List<AggregateResult> to List<AggregateResult>" which itself is not logical as the two types are the same. There are no compile errors on save.

Steps To Reproduce:

Type this code in apex class

        List<AggregateResult> noOpContracts = [SELECT MAX(Contract_Without_Opportunity_Cnt_Number__c) NoOppMaxNumber
                                               FROM Contract
                                               WHERE Contract_Without_Opportunity_Cnt_Number__c != null];

Filed Contract_Without_Opportunity_Cnt_Number__c is a numeric value. I am searching for the highest value across all records.

Expected result

No error is shown as the two types are the same, and the compiler doesn't show errors.

Actual result

I am getting a confusing error.

Hi @PawelWozniak Thanks for reporting the issue. Could you try the steps below and see if the warnings get disappeared?

1. delete the folder .sfdx/tools
2. reload VSCode workspace
3. after indexing completes, the warnings in the tab Problems should no longer exist.

Thank you.

Hi @mingxuanzhangsfdx I have applied the steps as suggested. Even closed and opened VSCode again, but no changes. Still, I see the same problem on the list.

Can you run SFDX: Refresh SObject Definitions from the command palette and see if that makes the error go away?

[PawelWozniak]

@daphne-sfdc Yes done that, output:

Starting SFDX: Refresh SObject Definitions

09:37:02.946 sf sobject definitions refresh
Processed 861 Standard sObjects
Processed 74 Custom sObjects
09:37:14.851 sf sobject definitions refresh
 ended with exit code 0

I waited a few minutes and no change, it is still shown.
