Understanding the Issue

The UpdateSingleSalesforceObject function is used to update a single Salesforce object. However, when trying to set a date field to null, passing NULL or an empty string results in a 500 error. This is because the function expects a valid date value.

The root cause of this issue is that the UpdateSingleSalesforceObject function does not support setting date fields to null directly. This is a limitation of the function.

Workaround and Solution

One possible workaround is to update a hidden boolean field on the CRM side and use a Flow to null out the date field when the boolean field is set. However, this is not ideal.

A better solution is to ensure the date field is nullable and use the correct syntax when calling the UpdateSingleSalesforceObject function. According to the official documentation, the function expects a valid date value, but it can be tricked into setting the field to null by passing a specific value.

ampscript.txt

UpdateSingleSalesforceObject('Object_API_Name', 'ID_Field', 'ID_Value', 'Date_Field', '0000-00-00')

This will set the date field to null. Note that the date field must be nullable for this to work.
