Features:

  • Simple update to the request body send to the command router, now includes "parameters" section.
  • Back-end does not set parameters individually via command router and 'set' command anymore.

Testing commands after changes:

Screencast.from.2026-08-14.17-45-44.webm

- Included parameters section on query request body.
- Removed usage of set and get commands/endpoints
- Removed old looping logic that sent multiple requests to the command-router to set parameters individually.

Review Change Stack

Caution

Review failed

An error occurred during the review process. Please try again later.

  • Adds parameters to query execution request bodies and removes the legacy per-parameter get/set command flow.
  • Normalizes query parameters, validates query text, preserves proxy JSON or text errors, and maps streamed query events to normalized responses.
  • No CLI, Docker/container lifecycle, config, secrets, Debian, or self-hosted runner changes are reported. Packaging and deployment behavior appears unchanged.
  • das-cli/tests/integration/test_command_router.bats covers command-router behavior, but no changes to das-cli/tests/ or dashboard component tests are identified. Verify coverage for the new parameter payload, normalization, error handling, and stream parsing.

Walkthrough

Query execution now sends collected parameters in one request. The backend validates and builds query payloads for the command router. Proxy responses and command events receive normalized data and error fields.

Changes

Query Execution Flow

Layer / File(s) Summary
Payload contracts and construction
das-dashboard/backend/shared/dtos/query_execution_dto.py, das-dashboard/backend/shared/utils/command_router_payload.py, das-dashboard/backend/tests/test_command_router_payload.py
QueryExecutionDto accepts optional parameters. Payload utilities validate query text, reject reserved parameters, normalize values, and construct router payloads. Tests cover these validations.
Backend execution and response normalization
das-dashboard/backend/controllers/query_controllers.py, das-dashboard/backend/services/query_services.py, das-dashboard/backend/shared/utils/parse_query_answer.py
The controller forwards parameters to query execution. The service accepts only query commands, builds the router payload, and converts payload errors. Proxy responses and command events are normalized.
Frontend parameter collection and request flow
das-dashboard/src/utils/queryParameters.js, das-dashboard/src/hooks/useQueryParameters.jsx, das-dashboard/src/hooks/useQueryExecution.js, das-dashboard/src/api/QueryAPI.js, das-dashboard/src/api/APIUtils.js
Parameter state is collected at execution time. startQueryExecution sends non-empty parameters with the query. Error extraction supports message, error, and structured error values.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to cc8d6

The query-parameter routing update is otherwise mergeable, but some command-router failures may be shown as a generic error instead of the actual server message, so the error-response handling should be corrected or explicitly accepted by the owner.

- Around line 142-143: Keep error messages string-valued at both affected sites:
in das-dashboard/backend/controllers/query_controllers.py lines 142-143,
serialize non-string content["error"] before assigning message while preserving
structured data in details; in das-dashboard/src/api/APIUtils.js lines 17-18,
serialize non-string data.error before extractErrorMessage returns it. Use the
existing error-handling symbols and preserve string values unchanged.

- Around line 19-20: Update the parameter merge in normalize_router_parameters
to reject the reserved query key before params.update, or restrict the merge to
an explicit allowlist that excludes query, while preserving the query generated
from command_text.

9-20: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Preserve proxy error text.

When err.response.data is a string, return that string instead of the fallback. Also handle data.content, because das-dashboard/backend/controllers/query_controllers.py Line 146 wraps invalid-JSON proxy responses in that field. Otherwise, users receive "An unexpected error occurred." instead of the proxy error.

Add tests for both response shapes.

Proposed fix
   if (typeof data === "string") {
-    return fallback;
+    return data;
   }

+  if (typeof data?.content === "string") {
+    return data.content;
+  }
+
   if (data?.message) {
