Oracle Text error when performing JSON API query

Affected Daml version

2.3.4 (previous ones were not tested)

Bug description

If the JSON API Server is being run with an Oracle query store, query on text field of the payload either results in 501 response, or returns an empty response. The query looks like the following:

{
  "templateIds": [
    "b0a685079d389146932b97f0556332083c4053612359518aeea1452c1d45e8a5:SIS.Main.SIRequest:SIRequest"
  ],
  "query": {
    "si_detail": {
      "si_input_no": {
        "%gt": ""
      }
    }
  }
}

When the failure happens, the response is: {"result":[],"errors":["Endpoints.ServerError: internal server error"],"status":501} DEBUG level log:

To reproduce

Start a sandbox. Startup a JSON API Service with Oracle query store. Create a contract of this template:

module SIS.Main.SIRequest where

import Daml.Script

data SIDetail = SIDetail with
  si_input_no : Text
    deriving (Eq, Show)

template SIRequest
  with
    requester : Party
    si_detail : SIDetail
  where
    signatory requester

Query on /v1/query using this payload:

{
  "templateIds": [
    "SIS.Main.SIRequest:SIRequest"
  ],
  "query": {
    "si_detail": {
      "si_input_no": {
        "%gt": ""
      }
    }
  }
}

The error seem to occur more reliably when multiple parties are allocated and a token with an act_as claim with all is used.

Expected behavior

Expected not to fail, also when not failing to return all contracts with non-empty si_input_no, like with a postgres query store, or without a query store.

I could not reproduce the error when a the disableContractPayloadIndexing=true is used at DB init. Although the result set is still empty.

Using an empty string should not matter, and it does not. I have tested it extensively. The same query against the JSON API server without a query store or against a PostgreSQL query store, returns appropriate results (interpreting the %gt as standard lexicographic ordering would govern it).

[S11001001]

#15022 should address the empty results when disableContractPayloadIndexing=true. It does not help with the Oracle Text error when the index is enabled.
