Problem with AQL on other_context extension cluster

[dileep-ehr]

EHRC - Complaints.zip
Please see the attached template set. We have added a custom cluster to extend the context information (openEHR-EHR-CLUSTER.ehrc_metadata.v0).
While building the AQL, if we include this in CONTAINS we get '204 No Content'.

{"aql":"select a/uid/value as uid, a/composer/name as author, a/name/value as concept, a/context/start_time/value as date_created, c/items[at0001]/value/magnitude as confidentialLeve FROM EHR e[ehr_id/value ='{{ehrId}}' ] CONTAINS COMPOSITION a[openEHR-EHR-COMPOSITION.encounter.v1] CONTAINS EVALUATION b[openEHR-EHR-EVALUATION.medication_summary.v0] AND CLUSTER c[openEHR-EHR-CLUSTER.ehrc_metadata.v0]"
}

We are able to get the result properly if we remove the cluster from CONTAINS and give full path in the AQL

{"aql":"select a/uid/value as uid, a/composer/name as author, a/name/value as concept, a/context/start_time/value as date_created, a/context/other_context[at0001]/items[openEHR-EHR-CLUSTER.ehrc_metadata.v0]/items[at0001]/value/magnitude as confidentialLeve FROM EHR e[ehr_id/value ='{{ehrId}}' ] CONTAINS COMPOSITION a[openEHR-EHR-COMPOSITION.encounter.v1] CONTAINS EVALUATION b[openEHR-EHR-EVALUATION.medication_summary.v0]"
}

We have tried different options for the CONTAINS, but are getting the same results

Interesting request. Would it be possible to get the operational template (.opt) and an example POST payload for a corresponding composition? Thanks
