Understanding Common Salesforce Errors
This is a running list of Salesforce errors that frequently cause skipped records on when syncing data to Salesforce. If you have an error we're missing, let us know!
DUPLICATES_DETECTED:Use one of these records?:--
This error is caused when attempting to insert a new Account, Contact, or Lead record that Salesforce thinks is a duplicate of a record already in Salesforce. That "Use one of these records?" message is actually the title of a message you'd see if you were trying to do this manually in Salesforce. Unfortunately, it's not that helpful as an error message!
Though Leads are separate objects from Contacts and Accounts, Salesforce has predefined duplication rules that check for duplicates between Lead and Contact/Account. You can see the rules that define duplicates and even define custom ones in Setup. Usually preventing duplicates is a great thing. The best way around this is to use Census's Multi-destination Syncs to sync to both Lead & Contact or Lead & Account at the same time.
In extreme cases, you can choose to turn off duplicate rules either only for the Census account, or entirely for your org. This is probably a bad idea, so proceed with caution!
CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY:MyCoolTrigger: System.LimitException: SBQQ:Too many SOQL queries: 101
Salesforce limits the number of SOQL queries that can be executed in individual batch transaction. Because Census uploads data in batches, any triggers associated with objects directly also need to handle large batches as well.
The primary cause of this problem is doing SOQL queries within a loop. The fix for this is straight forward, raise the SOQL queries outside the loop! Look for any other causes where you can get by with reusing the results of one query rather than requesting multiple times.
In some cases though, it can be hard to avoid many SOQL queries (Salesforce CPQ is built within the Salesforce platform for example and frequently runs into this error when handling batches). In this case, you'll need to use Apex's System.scheduleBatch() functionality to handle the trigger logic asynchronously. This gives you the flexibility to handle the changes in whatever batch size as appropriate to support your required number of SOQL queries.
INVALID_CROSS_REFERENCE_KEY:INVALID CROSS REFERENCE ID
This error shows up when a sync is attempting to create a relationship using a Salesforce ID that doesn't actually exist in the particular Salesforce installation. This could happen if you are accidentally using a different type of ID as a Salesforce ID, but most often, we see this when trying to use Salesforce IDs that exist in one Salesforce environment but not the destination, for example, using Salesforce IDs that exist in production but that do not exist in a Salesforce Sandbox.
