I am getting the following error from DupeBlocker, what does it mean and how can I resolve?
DupeBlocker has encountered an error. Please contact your Salesforce administrator with the following information:
*** Executing Method: DB_AutoConvert.asyncConvert
*** Exception Type: System.QueryException
*** Exception Cause: null
*** Exception Message: invalid ID field: null
This error occurs when DupeBlocker attempts to auto-convert a Lead into a matching Contact, but the Contact IS NOT associated with an Account, i.e. an "orphaned" Contact. Leads can ONLY be converted into Contacts that have an Account ID.
The resolution is to ensure all Contacts have an Account associated with them or add a Scenario filter to ONLY match to Contacts where the AccountID field is populated.
If there are legitimate cases where Contacts should be "orphans", then you will just need to understand that this error will occur and the Lead will not be converted in those instances.
NOTE: When manually converting a Lead to a matching "orphaned" Contact the conversion will hang (blank screen vs. seeing the Lead and Contact records).
