Error message
msg
What it means
jQuery.error is jQuery's generic error-raising helper: it simply throws new Error(msg). The message "msg" indicates an error was thrown through $.error with the literal/placeholder string 'msg', meaning calling code (often a plugin or jQuery internals like data/animation/attribute code) invoked $.error('msg') with an unhelpful or templated message. Any jQuery/plugin code path that detects an invalid state funnels through this throw.
Solutions
- Read the full stack trace to find the caller of $.error — that caller defines the real problem, not this throw site.
- Replace or fix the calling code that passes the literal 'msg'; supply a descriptive message or fix the invalid state it detected.
- Remove/fix the direct $.error('msg') call if it is placeholder code in your own source.
- Wrap the offending plugin call in try/catch if the failure is expected and can be handled gracefully.
Example fix
// before
$.error('msg'); // placeholder
// after
throw new Error('Expected a DOM element, got: ' + typeof el); Defensive patterns

Try / catch
try {

} catch (e) {
// jQuery.error throws plain Error; inspect the stack for the real $.error() caller
console.error('jQuery-level failure:', e.message, e.stack);
} Prevention
- Treat jQuery.error throws as signals from calling code — always read the stack trace above this frame.
- Replace placeholder $.error('msg') calls with descriptive messages or proper handling.
- Validate arguments passed to plugins (expected element types/options) before invoking them.
- Search your bundle for '$.error(' to find all throw sites when debugging.
When it happens
Trigger: Calling $.error('msg') directly in your code; plugin or jQuery internal code hitting an invalid condition and calling jQuery.error with a hard-coded or unformatted message (e.g. data storage on unsupported objects, invalid arguments to animation or cssHooks).
Common situations: Copy-pasted sample code where the placeholder string was never replaced; a plugin passing its message template unformatted; debugging session where the real call site is above this line in the stack trace.
