Merge page issue: SOQL Statements cannot query more than 35 different parent types

Error Message / Issue (value may differ) Cause of the issue Possible issue fix
SOQL Statements cannot query more than 35 different parent types. An unexpected error has occurred. Your solution provider has been notified. This error is triggered due to a Salesforce limit: Salesforce cannot query more than 35 lookup fields on a custom visual force page. (the Merge Page)  You can discard some of the lookup fields at DC Setup - Object settings - "Ignore these fields when merging". The fields selected will be ignored/not shown in the merging process but they will be merged by the rules defined in the Merge Rules page. To be able to use the page normally, try to fit under that 35 lookup fields limitation.

Remote Site settings error 403 - permission denied This error is usually triggered in the user's Sandbox environment because the profile/user do not have the sufficient permissions in his Production ORG to perform the API call in the Sandbox environment. The user needs to have your production org have the ‘API Enabled’ permission enabled in his Production ORG.

Other Issues





Apex CPU time limit exceeded



Error Message / Issue (value may differ) Cause of the issue Possible issue fix
CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY: dupcheck.dc3LeadTrigger: System.LimitException: Apex CPU time limit exceeded”.  This error is usually triggered when there are a lot of flows attached to the insert/update flows of an Object and the maximum CPU time limit for a record insert/update of 10sec is exceeded. It is not mandatory for the APP included in the error message to be the one causing it. Sometimes the app mentioned had the last executed flow, and it's shown as a messenger for that error. Enabling the 'Disable Triggers' setting and enabling the 'small trigger footprint' setting at the DC Settings page. This will disable all ordinary DC triggers and enable the small triggers which use less CPU time.





Attempt to de-reference a null object


Error Message / Issue Cause of the issue Possible issue fix
Error Message: “An embedded page *page link* Attempt to de-reference a null object. “ This issue is triggered when an Object, Custom Object, Record Type.. etc. is removed/deleted from the Org but it's still configured in Duplicate Check Setup. 

The Object is not existing anymore and DC crashes because of corrupted configuration. 
1. The user can run a DC Setup Check ( 'DC Setup Check' from DC Setup -> Setup Check) to solve the issue. 

2. If it's a Record Type, before its removal from the org, to prevent future issues, the user needs to navigate to the Objects Records Types tab on the DC Setup page and set all settings to 'nothing selected' for the record type he wants to delete.




"Disable Duplicate Check" checkbox not working on the Accounts Object



Error Message / Issue Cause of the issue Possible issue fix
The "Disable DC Checkbox" is not working as intended in the Account Object layout page. The wrong "Disable DC Checkbox" custom field was deployed in the Account Layout. If you are using Person Accounts, there are 2 "Disable DC Checkboxes" custom fields available for deployment on the Account Layout. 
The correct custom field deployed on the Account Layout should be with API name "dupcheck_dc3DisableDuplicateCheck_c" (c - Custom) and not "dupcheckdc3DisableDuplicateCheck_pc" (c- Person Custom)
