it seems in your start form you have a property named "approver" of type "user" but the formType "user" is unknown for the engine.

you should register this custom type as follows:
<code>
processEngineConfiguration.setCustomFormTypes(formTypes);
</code>

or with XML:

<code>
<bean id="processEngineConfiguration" class="…..">
<property name="customFormTypes">
                    <list>
                        <bean class="<your UserFormType fully qualified class name>"/>
                    </list>
                </property>
</bean>
</code>

Thank you so much for the reply. I actually tried to look for what you mentioned in my process but did not find anything like that. But something went definitely wrong in my process definition. May be some wrong variable or something like that

To resolve this issue, I built the process from scratch again and tested it through my web application after adding every 2-3 steps. This way I was sure that process is right at least till this step. And went on building and testing it till end step by step. And finally got it executed without any issue.
