Error message

Name cannot be empty

What it means

HTTP 400 raised by POST /api/gallery/{image_id}/rename when the submitted name is empty after stripping whitespace. The handler reads data['name'], applies (data.get('name') or '').strip() and rejects falsy results, so '', ' ', null, and a missing 'name' key all fail identically.

Solutions

1. Require a non-blank name in the UI before enabling submit.
2. Send the field as exactly "name" with at least one non-whitespace character.
3. Trim client-side and skip the request entirely when empty.

Example fix

// before
await post(`/api/gallery/${id}/rename`, {name: input.value});
// after
const name = input.value.trim();
if (!name) return showError('Enter a name');
await post(`/api/gallery/${id}/rename`, {name});

const name = (input?.value ?? '').trim();
if (!name) return showError('Enter a name');
await post(`/api/gallery/${id}/rename`, {name});

const isNonBlankName = (v) => typeof v === 'string' && v.trim().length > 0;

When it happens

Trigger: Sending {"name": ""}, {"name": " "}, {}, or {"name": null} in the JSON body of the rename request.

Common situations: UI rename dialog submitted without typing anything; double-submit clearing the input; frontend sending the wrong key (e.g. 'title') so .get() returns None.
