[midPoint] Error with inbound mapping in latest build.

[Deepak Natarajan]

Hi Everyone -

I just deployed the latest build and one of my inbound mappings from a
CSV resource is failing :

                <attribute>
                    <ref>ri:orgdesc</ref>
                    <inbound>
                        <expression>
                            <script>
                               
<language>http://www.w3.org/TR/xpath/</language>
                                <code>
                                    tokenize($c:input,"/")[last()]
                                </code>
                            </script>
                        </expression>
                        <target>
                           
<path>$user/extension/apos:aposUnitAttributes</path>
                        </target>
                    </inbound>
                </attribute>

I fiddled around and changed it to this :

                    <ref>ri:orgdesc</ref>
                    <inbound>
                        <expression>
                            <script>
                                <code>
                                    return input?.split("/")?.last()
                                </code>
                            </script>
                        </expression>
                        <target>
                           
<path>$user/extension/apos:aposUnitAttributes</path>
                        </target>
                    </inbound>

And it fails. The error is :

I actually have another installation of Midpoint 3.0 where this is
running and working correctly (I haven't touched this mapping in ages).

Is there anything that could break this in the latest version?

Thanks!
