Description

Mock response names accepted almost anything: special characters, over-long text, duplicates and surrounding spaces.

Problem
Invalid, duplicate and space-padded names taken as the response name.

Fix
One shared rule now blocks invalid names, duplicates and stray spaces inline, before anything saves.

Walkthrough

Mock response creation, renaming, and saving now use Formik, Yup, centralized name validation, duplicate checks, trimmed names, and current-response exclusion.

Changes

Mock response validation flow

Layer / File(s) Summary
Shared validation schemas
packages/bruno-app/src/utils/mock-server/mock-responses.js, packages/bruno-app/src/utils/mock-server/mock-responses.spec.js
Centralized name validation checks required values, allowed characters, case-insensitive duplicates, and excluded response UIDs. Description validation is exported as a Yup schema constant.
Create modal Formik workflow
packages/bruno-app/src/components/MockServer/MockResponse/CreateMockResponseModal/index.js
Formik manages form values, example selection, validation, submission state, errors, trimmed values, and linked status and body type fields.
Rename and save integration
packages/bruno-app/src/components/MockServer/MockResponse/RenameMockResponseModal/index.js, packages/bruno-app/src/components/MockServer/MockResponse/MockResponseTopBar/index.js, packages/bruno-app/src/components/MockServer/MockResponse/index.js
Rename and save flows use shared validation, pass the current response UID, exclude the current response from duplicate checks, and disable confirmation controls for invalid or blank names.

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

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Reject surrounding spaces before normalization.

Line 363 trims name before validation. As a result, ' response ' validates as 'response'. The create, rename, and edit flows accept the value and persist a different name.

Validate the raw value for surrounding spaces before trimming it.

Proposed fix
-  const value = name == null ? '' : String(name).trim();
+  const rawValue = name == null ? '' : String(name);
+  if (!rawValue.trim()) {
+    return validateNameError('');
+  }
+  if (rawValue !== rawValue.trim()) {
+    return 'Name cannot start or end with a space.';
+  }
+  const value = rawValue.trim();

Clear submission status when example controls change.

After a failed creation, formik.status is displayed through nameError. The example handlers change the name or selection without clearing formik.status. Selecting another example or toggling example mode can therefore leave the previous server error under the Name field. Call formik.setStatus(null) in both handlers.

231-236: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Validate the original name before trimming it.

Line 231 removes surrounding spaces before getMockResponseNameValidationError runs. The shared rule therefore cannot reject leading or trailing spaces in the edit-save workflow. Validate the original name first, then trim only after validation succeeds.

Proposed fix
-      mockResponse.name = mockResponse.name.trim();
-
       const validationError = getMockResponseNameValidationError(mockResponse.name, {
         existingResponses: responses,
         excludeUid: responseUid
       }) || getMockResponseDescriptionError(mockResponse.description);
       if (validationError) {
         toast.error(validationError);
         return;
       }
+
+      mockResponse.name = mockResponse.name.trim();
