Attributes must be valid JSON

Error message

Attributes must be valid JSON

What it means

The optional attributes field failed the isJson check, so VADD ... SETATTR is never sent. SETATTR expects a JSON object; the client refuses malformed JSON client-side, mirroring error 103 but for the attribute box.

Solutions

Use strict JSON: double-quoted keys and string values, no trailing commas
Validate the attributes in a JSON linter before saving

Defensive patterns

Strategy: validation

Validate before calling

if (attrs && !isJson(attrs)) {
  return this.$message.error('Attributes must be valid JSON');
}

function isJson(str) {
  try { JSON.parse(str); return true; } catch (_) { return false; }
}

Type guard

function isJsonObject(str) {
  if (typeof str !== 'string' || !str.trim()) return false;
  try { const v = JSON.parse(str); return v !== null && typeof v === 'object' && !Array.isArray(v); } catch (_) { return false; }
}

Prevention

Validate optional JSON fields exactly like required ones — an empty value is fine, a malformed one is not
Lint attributes with JSON.parse and show the parse position on failure
Accept only objects for SETATTR to match Redis expectations

When it happens

Trigger: Single-quoted keys, unquoted keys, trailing commas in the attributes box; a half-edited object; pasting Python dict syntax.

Common situations: Metadata pasted from Python dicts or YAML; quick edits leaving a dangling comma.
