Root Cause

None of the function's overload signatures match the provided arguments. Check each overload's requirements.

generic

Workarounds

  1. 92% success Read each overload signature in the error — match your args to one of them 
    // Read the error carefully — it lists each overload:
// Overload 1 of 3: (a: string, b: number) => void
// Overload 2 of 3: (a: number) => void
// Overload 3 of 3: (a: Config) => void

// Match your arguments to one of them:
myFunction('hello', 42);  // matches overload 1
myFunction(42);            // matches overload 2

  2. 88% success Check for subtle type differences: string vs String, number vs bigint 
    string vs String, number vs bigint

  3. 85% success Common with event handlers: use the specific event type, not generic Event 
    onClick: (e: React.MouseEvent<HTMLButtonElement>) => void

Dead Ends

Common approaches that don't work:

  1. Cast arguments to any 80% fail

    Bypasses type checking entirely — the overloads exist for correctness

  2. Remove the overload signatures 85% fail

    If it's a library function, you can't modify it
