I'm trying to use the Salesforce output connector to insert new Customer records and keep receiving this error message.

However, this field DOES exist, as shown below:

It also doesn't appear on the Input connector, which is another issue as I need this field to join my data.

I need this field for what I'm attempting to do. Any suggestions on how to get the connectors to recognize the existing field? I've tried deleting the connectors and re-adding them and also restarting Alteryx Designer, with no luck.
