Error in Optimizer & Clone: Access violation by field ADvendio__ProposalLineItemId__c

Deprecated and removed objects/fields/buttons

Solution:

There are two known workarounds: remove the field from profile and permission sets (this could be time consuming if there are multiple permission sets and profiles). Or the quickest workaround is to delete the field, following these steps:

• Switch to Salesforce classic

• Click setup on the top right

• On the left hand side see Build-> Create-Objects-> click Objects

• Search for "Campaign Item" and click on the link

• Under Custom Fields & Relationships find the field "ADvendio__ProposalLineItemId__c"

• There will be a button to delete it on the left - Click delete and confirm
