Error message

msg

What it means

jQuery.error is jQuery's generic error-raising helper: it simply throws a new Error with the supplied message. It is the internal mechanism behind many jQuery failures (e.g. via $.fn.html template parsing or Deferred exception propagation), so this throw site means some jQuery code path called $.error('...') with a specific message.

Solutions

1. Read the full Error message and stack below this frame to find the jQuery API that called $.error; fix the arguments passed there.
2. Wrap the offending jQuery call in try/catch to intercept the thrown Error and log/report it.
3. Check jQuery upgrade notes if a previously-working call now throws; behavior can change between 3.5.1 and 3.6.0.

Example fix

// before
$('#el').html(someUntrustedString); // may surface via $.error
// after
try {
  $('#el').html(someUntrustedString);
} catch (e) {
  console.error('jQuery call failed:', e.message);
}

// Validate inputs to jQuery APIs before calling them:
if (typeof selectorOrHtml !== 'string' || !selectorOrHtml.trim()) {
  throw new Error('Refusing to call jQuery with empty/invalid input');
}

function isNonEmptyString(v) { return typeof v === 'string' && v.length > 0; }

try { $(input).doSomething(); } catch (e) { if (e instanceof Error && e.message) { report('jQuery $.error thrown: ' + e.message); } else { throw e; } }

When it happens

Trigger: Any internal jQuery code path that detects a bad input and calls $.error(message) — e.g. malformed template/HTML passed to html(), unsupported selector cases routed to error(), or invalid arguments to methods that delegate their failure reporting to jQuery.error.

Common situations: Reading a stack trace where the top frame is jQuery.error and the real message is in the thrown Error's message property; the actual offending call is the second frame in the stack, not line 334 itself.

Understand the failure class

Background: "Must be a positive integer", "Invalid value", "Unsupported": the invalid-argument-value error family, when a library rejects the value you pass — this error's family across 35 libraries.
