Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the user experience and robustness of the agentflow UI by introducing a flexible HTTP node body editor, improving the dynamic rendering capabilities of array inputs, and addressing several validation issues. These changes streamline the process of configuring complex nodes, prevent common crashes, and provide more informative UI elements, making the platform more intuitive and reliable for users.

Highlights

New HttpBodyInput Component: Introduced a new HttpBodyInput component that dynamically renders either a textarea (for JSON/raw body types) or a key-value array editor (for formData/xWwwFormUrlencoded body types) for the HTTP node's body field.
Enhanced Array Input Visibility: Improved the ArrayInput component to support nested array rendering and $index-based field visibility, specifically for the Start node's Form Input mode, allowing for more complex and dynamic forms.
Validation Fixes: Addressed several validation issues, including fixing a crash in computeArrayItemParameters when a non-array field changed, ensuring validateNode resolves input parameters from availableNodes when node.data.inputs is missing, and making validateNode respect param.default values for required field checks.
Improved Options Dropdown: Added functionality to render option.description in options dropdowns, providing more context to users when selecting options.

Code Review

This pull request introduces a new HttpBodyInput component for conditional rendering of HTTP node body editors, supporting rich text for JSON/raw types and array inputs for form data. It enhances the NodeInputHandler to display descriptions for select options and updates the InputParam type to include an optional description field. Additionally, the PR improves node validation by considering default values for required fields and prioritizing schemas from availableNodes. Several new test cases were added for ArrayInput to cover nested array visibility, for HttpBodyInput to ensure its functionality, and for EditNodeDialog to verify dynamic itemParameters computation and prevent crashes when non-array fields change. The jest.config.js was updated to include coverage for the new HttpBodyInput component.

Code Review

This pull request introduces several valuable features and fixes. The new HttpBodyInput component provides a flexible UI for the HTTP node's body, and the support for nested arrays with indexed visibility is a great enhancement. The fixes to the validation logic, including using availableNodes for schema information and respecting default values, improve the robustness of the system. The crash fix in computeArrayItemParameters is also a welcome improvement. The code quality is high, and the changes are well-tested. I have no further comments.

show only label as selected value (exclude descriptions)

display dropdown with label and descriptions (if available), this is the behaviour of Start Node in agentflow v2

+            const baseParams = nodeSchema?.inputs || node.data.inputs || []
+
+            // The credential field is a separate property on the node schema (not in inputs).
+            // Prepend it to inputParams so the dialog renders it.


this is especially the case for Start node. The change below will render credential field in Start node (in addition to Agent/LLM node)

Note that we don't support Create New Credentials yet, this will be done in a separate task.

        if (param.type === 'array' && param.array) {
-            const items = (inputValues[param.name] as Record<string, unknown>[]) || []
+            const raw = inputValues[param.name]
+            const items = Array.isArray(raw) ? (raw as Record<string, unknown>[]) : []


fix a bug on HTTP node body type field selection, select JSON or raw will throw an error and broke UI

jocelynlin-wd · 2026-03-20T21:38:27Z

packages/agentflow/src/core/validation/flowValidation.ts

        // evaluateParamVisibility correctly uses those values to resolve show/hide conditions on
        // dependent fields, so async-driven visibility is handled automatically here.
-        if (!param.optional && evaluateParamVisibility(param, inputValues) && isEmptyValue(inputValues[param.name])) {
+        if (!param.optional && evaluateParamVisibility(param, inputValues) && isEmptyValue(inputValues[param.name] ?? param.default)) {


if user does not specifically select a value in dropdown, validation will show an error. This is inconsistent with agentflow v2 which accepts default value as the field value.

Tested HTTP node body type switching (json/raw/formData/xWwwFormUrlencoded), credential field visibility, variable support, and validated no false required warnings on fresh nodes. Also verified Start node nested array visibility per row 👍

jchui-wd

Tested locally:
Start node dropdown descriptions, HTTP node credential field, and Execute Flow JSON input all working as expected.
