Hi All, I am getting the following error when invoking new user approval REST API in IS-5.9.0-M6-SNAPSHOT, which is built with carbon kernel-4.5.0-M4 at first server startup.
Caused by: <openjpa-2.2.0-wso2v1-r128166:129108 nonfatal user error> org.apache.openjpa.persistence.ArgumentException: An error occurred while parsing the query filter "SELECT COUNT(DISTINCT t) FROM org.wso2.carbon.humantask.core.dao.jpa.openjpa.model.Task t JOIN t.humanRoles hr JOIN hr.orgEntities oe WHERE oe.name IN :names AND hr.type = :roleType AND t.type = :taskType AND t.tenantId = :tenantId AND t.status IN :taskStatuses". Error message: The name "org.wso2.carbon.humantask.core.dao.jpa.openjpa.model.Task" is not a recognized entity or identifier. Perhaps you meant PresentationDescription, which is a close match.

However, when I invoke the REST endpoint again after invoking SOAP service, the error gets resolved and works as expected. Below is a sample curl to invoke the REST endpoint. curl -X GET " https://localhost:9444/t/carbon.super/api/users/v1/me/approval-tasks?status=READY"; -H "accept: application/json" -H "Authorization: Basic YWRtaW46YWRtaW4=" -k Following is the SOAP request made prior to getting the issue somehow. https://localhost:9443/services/HumanTaskClientAPIAdmin/ > > <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"; > xmlns:ns=" > http://docs.oasis-open.org/ns/bpel4people/ws-humantask/api/200803"; > xmlns:ns1=" > http://docs.oasis-open.org/ns/bpel4people/ws-humantask/types/200803";> > <soapenv:Header/> > <soapenv:Body> > <ns:simpleQuery> > <ns:simpleQueryInput> > <!--Zero or more repetitions:--> > <ns1:status>READY</ns1:status> > <ns1:status>RESERVED</ns1:status> > <ns1:status>COMPLETED</ns1:status> > <ns1:simpleQueryCategory>CLAIMABLE</ns1:simpleQueryCategory> > </ns:simpleQueryInput> > </ns:simpleQuery> > </soapenv:Body> > </soapenv:Envelope> The above REST API is working on the pack build on top of kernel-4.5.0-M2, without any issue. Appreciate if you can have a look on this.
