AQL issue when selecting content

Implementation
1

I am trying do query some detailed parameters using AQL. I am trying to select by content, like:

SELECT c FROM EHR e CONTAINS COMPOSITION c WHERE c/content/archetype_node_id = 'openEHR-EHR-SECTION.adhoc.v1'"

But then response from EHRBASE is

Could not process query/stored-query, reason: java.lang.StringIndexOutOfBoundsException: begin 0, end -1, length

In whole composition it is as below (excerpt):

     },
    "archetype_node_id": "openEHR-EHR-COMPOSITION.health_summary.v1",
    "content": [
        {
              "name": {
                  "value": "History of present illness section",
                  "_type": "DV_TEXT"
              },
              "archetype_node_id": "openEHR-EHR-SECTION.adhoc.v1",
              "_type": "SECTION",
              "items": [
                  {
                      "name": {
                          "value": "History of present illness",
                          "_type": "DV_TEXT"
                      },

But when my query is:

SELECT c FROM EHR e CONTAINS COMPOSITION c WHERE c/archetype_node_id = 'openEHR-EHR-COMPOSITION.health_summary.v1'

Then it is ok. My suspicion relates to the square parenthesis on the content section, but I am not sure. How to filter content data?

Thank you,

This looks like it is a bug in ehrBase which I suggest you report, as it works as expected in the BetterCDR.

However you can achieve the same goal with

SELECT c FROM EHR e CONTAINS COMPOSITION c CONTAINS SECTION s[openEHR-EHR-SECTION.adhoc.v1]
