ARGUMENT_ERROR

Error message

Memory name cannot be empty or whitespace.

What it means

Validation in create_memory: the 'name' field, after strip(), is empty. Names consisting only of whitespace (or empty strings) are rejected with ArgumentException (HTTP 400) before any row is inserted.

Solutions

1. Trim the name client-side and require non-empty before calling the API
2. Give the input a sensible default name when the user leaves it blank
3. Add form validation (required attribute) so the request never leaves the browser

Example fix

# before
create_memory({"name": " ", ...})

# after
name = raw_name.strip() or f"Memory-{date.today()}"
create_memory({"name": name, ...})

name = (payload.get("name") or "").strip()
if not name:
    payload["name"] = f"Memory-{uuid4().hex[:8]}"

def is_nonblank_name(v) -> bool:
    return isinstance(v, str) and len(v.strip()) > 0

try:
    create_memory(payload)
except ArgumentException as e:
    if "empty or whitespace" in str(e):
        payload["name"] = default_name()
        create_memory(payload)

When it happens

Trigger: POST create-memory with name="", name=" ", or a name of only tabs/newlines. The value is stripped before the length check, so ' ' fails.

Common situations: Forms submitted without the name field populated; trimming done only client-side and bypassed by direct API calls; default empty-string values leaking from config objects.
