Shibboleth nameID format emailaddress

I am working on integrating a SAML vendor (Freshdesk) into my Shibboleth environment. My issue is the nameID format is empty.

Reading through the documentation on my vendor, they want <saml:NameID Format="urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress">[email protected]</saml:NameID>

I've added this format to my metadata, as well as inside an attribute encoder in my attribute definition for email.

However in my debug logs I am getting this message:

I have been unable to find the cause of the AddNameIDToSubjects error, why is it leaving the NameID empty? Is it a problem with my Attribute Encoder? 

 <resolver:AttributeDefinition id="email" xsi:type="ad:Simple" 
              sourceAttributeID="mail" >
        <resolver:Dependency ref="psdldap" />


        <resolver:AttributeEncoder 
                xsi:type="enc:SAML2StringNameID" 
                xmlns="urn:mace:shibboleth:2.0:attribute:encoder" 
                nameFormat="urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress" />

        <resolver:AttributeEncoder 
                xsi:type="enc:SAML1String" 
                name="urn:mace:dir:attribute-def:email"/>
        <resolver:AttributeEncoder 
                xsi:type="enc:SAML2String" 
                nameFormat="urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress" 
                name="urn:oid:0.9.2342.19200300.100.1.3" friendlyName="email"/>
    </resolver:AttributeDefinition>

SAML2AttributeSourcedGenerator should be configured in saml-nameid.xml 

<!-- SAML 2 NameID Generation -->
<util:list id="shibboleth.SAML2NameIDGenerators">

    <ref bean="shibboleth.SAML2TransientGenerator" />

    <!-- Uncommenting this bean requires configuration in saml-nameid.properties. -->
    <!--
    <ref bean="shibboleth.SAML2PersistentGenerator" />
    -->

    <bean parent="shibboleth.SAML2AttributeSourcedGenerator"
        p:format="urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress"
        p:attributeSourceIds="#{ {'email'} }" />

</util:list>

More details in Shibboleth Wiki in Custom Identified Configuration section.
