  Predicate may detach the buffer

  22.2.3.11 %TypedArray%.prototype.findIndex ( predicate [ , thisArg ] )

    %TypedArray%.prototype.findIndex is a distinct function that implements the
    same algorithm as Array.prototype.findIndex as defined in 22.1.3.9 except that
    the this object's [[ArrayLength]] internal slot is accessed in place of
    performing a [[Get]] of "length".

    ...

  22.1.3.9 Array.prototype.findIndex ( predicate[ , thisArg ] )

    Repeat, while k < len,
      Let Pk be ! ToString(F(k)).
      Let kValue be ? Get(O, Pk).
      Let testResult be ! ToBoolean(? Call(predicate, thisArg, « kValue, F(k), O »)).
    ...

  IntegerIndexedElementGet ( O, index )

    Let buffer be the value of O's [[ViewedArrayBuffer]] internal slot.
    If IsDetachedBuffer(buffer) is true, return undefined.
