dileep-ehr opened a new issue, #12960: URL: https://github.com/apache/apisix/issues/12960
### Current Behavior We are trying to use APisix as a gateway for our FHIR server. FHIR searches can include "|' in their query params like below `/ehrn/abdmc/v1/nhcxtest/Task?identifier=http://hospital.com/trace-ids|TRC-998877` But I am getting error as below `115.99.165.197 - - [23/Jan/2026:16:05:53 +0530] <server url> "GET /ehrn/abdmc/v1/nhcxtest/Task?identifier=http://hospital.com/trace-ids%7CTRC-998877 HTTP/1.1" 400 435 0.023 "-" "PostmanRuntime/7.49.1" 172.21.10.9:8080 400 0.001 "<serverurl>/fhir/nhcxtest/Task?identifier=http://hospital.com/trace-ids%7CTRC-998877"` From my exploration, I think the issue is because Apisix is not decoding the encoded special characters in the queryparam, while it does decode the ones in the uri, before forwarding to FHIR server, which receives the request parameter with the encoded "|" ### Expected Behavior The special characters in the query params encoded by https clients should be decoded like the ones in uris, before forwarding to the backend services ### Error Logs _No response_ ### Steps to Reproduce 1. Run apisix in docker 2. Run HAPI fhir server in docker 3. Create a route to the FHIR server 4. Send a search using queryparams containing '|" ### Environment - APISIX version (run `apisix version`): - Operating system (run `uname -a`): - OpenResty / Nginx version (run `openresty -V` or `nginx -V`): - etcd version, if relevant (run `curl http://127.0.0.1:9090/v1/server_info`): - APISIX Dashboard version, if relevant: - Plugin runner version, for issues related to plugin runners: - LuaRocks version, for installation issues (run `luarocks --version`): -- This is an automated message from the Apache Git Service.
