Daily message limit must be null or a number greater than or

Error message

Daily message limit must be null or a number greater than or equal to 1

What it means

Thrown by User.validations.dailyMessageLimit when the value is non-null but Number(value) is NaN or less than 1. null is explicitly allowed (means 'no limit'). The validator runs in User.create (line 133) and the value is cast via castColumnValue for storage.

Solutions

1. Pass null (or omit the field, since the default is null) to mean 'no limit'.
2. Pass an integer >= 1 to set a cap.
3. Coerce ambiguous inputs: treat 0/empty as null before validation.

Example fix

// before
User.create({ username, password, dailyMessageLimit: 0 });
// after
User.create({ username, password, dailyMessageLimit: null });

function normalizeDailyLimit(v) {
  if (v === null || v === '' || v === undefined) return null;
  const n = Number(v);
  if (isNaN(n) || n < 1) return null;
  return n;
}

const isValidDailyLimit = (v) => v === null || (typeof v === 'number' && !isNaN(v) && v >= 1);

When it happens

Trigger: Creating/updating a user with dailyMessageLimit set to 0, a negative number, a non-numeric string (e.g. 'unlimited', 'abc'), or the string 'null'.

Common situations: Frontend sends 0 intending 'disabled' instead of null. API client sends an empty string that Number() coerces to 0 or NaN. Import script misreads a blank column as 0.
