Error message

eastmoney convertible --limit must be an integer between 1 and 100

What it means

parseConvertibleLimit() normalizes the --limit option (default 20, valid range 1–100). When given a number it must be an integer within 1..100; otherwise it throws ArgumentError. Line 50 fires when a numeric value is passed that is a non-integer (e.g. 2.5) or out of range (0, -1, 101, NaN).

Solutions

1. Pass an integer between 1 and 100 inclusive.
2. Use Math.round/Math.floor on computed values before passing.
3. Omit --limit entirely to use the default of 20.
4. Clamp user input to the 1..100 range in your own code first.

Example fix

// before
const limit = Math.ceil(total / pages); // may be float or out of range
// after
const limit = Math.min(100, Math.max(1, Math.round(total / pages) || 20));

function validLimit(n) { return Number.isInteger(n) && n >= 1 && n <= 100; }
if (!validLimit(limit)) limit = 20;

const isValidLimit = (v) => (typeof v === 'number' && Number.isInteger(v) && v >= 1 && v <= 100) || (typeof v === 'string' && /^\d+$/.test(v.trim()) && Number(v) >= 1 && Number(v) <= 100);

try {
  rows = await eastmoneyConvertible({ limit });
} catch (e) {
  if (e instanceof ArgumentError && /--limit/.test(e.message)) {
    console.error('Invalid --limit: use an integer 1-100 (default 20).');
  } else throw e;
}

When it happens

Trigger: --limit=0, --limit=101, --limit=2.5, or programmatically passing NaN (which is typeof 'number', fails Number.isInteger) to the convertible command.

Common situations: Scripting the CLI with a computed limit that divides to a float; off-by-one when wanting 'all rows' and passing 0 or a huge number; NaN leaking from parseInt on bad input.
