Meaning

Read each overload's error: the last or most relevant one explains which argument fails. Fix argument types (string vs number, undefined from optionals), narrow values first, or pass options in the right shape. In React (useState, style, event handlers), a wrong prop type triggers it.

Common causes

  • Argument types don't match any overload
  • Possibly undefined value passed
  • Wrong options object shape
  • Library overloads changed in upgrade
  • Event handler types mismatch

⚡ Quick fix

  1. Narrow/convert arguments to the expected type
  2. Read each overload's message (the 2nd line)
  3. Check library version typings

Detailed fix by platform

TypeScript

  1. const el = document.getElementById("a"); if (el) el.addEventListener("click", handler);

How to diagnose

  1. Overloads — Which fail?
  2. Argument — Undefined/wrong?
  3. Version — Typings?
