Salesforce Sync Error: Unable to update campaign member status
We are receiving the following error when people respond to a campaign:
Why: Marketo is unable to update Campaign Member Status in Salesforce
Error details:
System.QueryException:Non-selective query against large object type
It does not impact everyone who has a change in the campaign member status for that campaign and I have not been able to identify a pattern. I don't understand what the Error details mean and we have not been able to find ant issues in Salesforce. The campaign member status we are changing to is in the Salesforce campaign and other members are able to have their status updated. Any ideas on how to fix or further troubleshoot this issue?
