I am trying to populate the Postal Address attribute with this rule

<?xml version="1.0" encoding="UTF-8"?><policy>
<rule disabled="true">
<description>Add attribute</description>
<conditions>
<and>
<if-class-name op="equal">User</if-class-name>
</and>
</conditions>
<actions>
<do-add-dest-attr-value class-name="User" name="Postal Address">
<arg-value type="string">
<token-op-attr name="SA"/>
</arg-value>
</do-add-dest-attr-value>
</actions>
</rule>
</policy>

I have the new value in the document but I get an error -641
ERR_INVALID_REQUEST
