app.error_session_name_required

Error message

app.error_session_name_required

What it means

renameSessionTitle validates that the new session title is non-empty after trimming whitespace. An empty or whitespace-only title cannot identify the session in the sidebar, so the localized message 'app.error_session_name_required' is thrown before calling options.renameSession.

Solutions

1. Trim and validate the title in the UI before calling renameSessionTitle; disable the confirm button while trimmed title is empty.
2. Pass a fallback title (e.g. 'Untitled session') when input is blank.
3. Catch the error and show the localized validation message in the rename dialog.

Example fix

// before: await store.renameSessionTitle(id, input.value) | // after: const title = input.value.trim(); if (title) await store.renameSessionTitle(id, title)

const title = newTitle.trim(); if (!title) { showToast(t('app.error_session_name_required')); return; } await store.renameSessionTitle(sessionID, title);

try { await store.renameSessionTitle(sessionID, title); } catch (e) { if (e.message.includes('error_session_name_required')) { setRenameError(t('app.error_session_name_required')); } else { throw e; } }

When it happens

Trigger: Calling renameSessionTitle(sessionID, title) with title = '' or a string of only whitespace (e.g. the user cleared the rename input and pressed Enter).

Common situations: Rename dialog allowing an empty submit; programmatic rename from an automation with an unset title variable; pasting only spaces or invisible characters into the rename field.
