I am creating an SOAP upsert request and attempting to use the fieldsToNull tag to blank out a date field after it has already been given a value. I keep getting an INVALID_FIELD error. Bellow is the code snippet.
<fieldsToNull> dateField__c </fieldsToNull>
After sending the request the response throws and error as shown below.
<faultstring> INVALID_FIELD: No such column ' dateField__c' on entity 'Contact'. If you are attempting to use a custom field, be sure to append the '__c' after the custom field name. Please reference your WSDL or the describe call for the appropriate names. </faultstring>
I have checked spelling for the field and copied the API field label. I have also checked field accessibility and security to the user account making the change and it has read and editable access to that field. I saw on some other questions that this could be a pre version 28 issue, however SOAP version 33 is what we are using.
What else am I missing to still receive this error? And is there another way to blank, or null out this date field using a SOAP upsert request after the field has been given a value?
