Read through the following topic if you experience the error: The length of the result output, 1, did not match the number of inputs, 2, for the Connector Update operation in process 1. Acoustic Campaign to MS CRM - Lead Sync.
The error usually occurs in a map where Acoustic Campaign is the Source and CRM is the Target. The error suggests the number of records in Acoustic Campaign was set to update or insert, based on the matching criteria and status of the records, did not match how many wereavailable for update.
Resolving the problem
This can happen if a CRM record was deleted, qualified, or deactivated before Acoustic Campaign could update it. CRM does not allow updates to deactivated records. When a record is deleted in CRM, it can no longer be matched with a record that was added to Acoustic Campaign from CRM.
If the records are discovered, in the Query block of the affected map, advance the date and time when the record was processed. Bypass the date and time of the faulty record to allow the sync to continue. Even if the records are not immediately discovered it still exists in Acoustic Campaign database can be used for research by the CRM Admin. Open a Support Portal case with the CRMi team for resolution assistance.
