Error message

msg

What it means

jQuery 3.6.0's $.error helper throws a new Error with whatever message is passed — the same generic throw site as 3.5.1 (line shifted to 338 in this build). It is not a distinct failure mode; it reports errors on behalf of other jQuery code paths.

Solutions

1. Inspect e.message and the next stack frames to identify the jQuery API call that invoked $.error, and fix its inputs.
2. Wrap the implicated call in try/catch to capture and report the error context.
3. Check the 3.6.0 upgrade guide / breaking changes if the same call worked on 3.5.1, and adjust usage or pin the previous version temporarily.

Example fix

// before
$('#target').append(userHtml); // failure reported via $.error
// after
try {
  $('#target').append(userHtml);
} catch (e) {
  console.error('jQuery 3.6 call failed:', e.message);
}

if (!isNonEmptyString(arg)) throw new Error('Refusing jQuery call with empty input');
function isNonEmptyString(v) { return typeof v === 'string' && v.length > 0; }

function isSafeHtmlString(v) { return typeof v === 'string' && !/\<\s*script/i.test(v); }

try { $('#el').call(input); } catch (e) { captureError(e, { context: 'jquery-3.6.0 $.error', message: e.message }); }

When it happens

Trigger: Internal jQuery 3.6.0 paths calling $.error(message) upon invalid input — e.g. bad markup in html(), invalid method arguments, or failures surfaced through deferred chains.

Common situations: Stack traces whose top frame is this helper after upgrading to 3.6.0; the real cause is in e.message and the caller frames below.

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.
