Sentry error - IndexSizeError: The index is not in the allowed range

I am getting this error from Sentry repetitively in ios - safari 14.0 in react project.

There is no code trace and no other information than this but it repeats in almost every URL.

I have already searched for the options everywhere. I have tried debugging but I can't replicate it, and so I can't resolve it.

Does anyone know what does this error means? Or how can I add debug information in Sentry?

I have been looking for the solution for a while and couldn't get it. I know it's a bit lack of information to provide but that's why I am asking this. if someone can tell me how to deal with sentry errors if you don't know why it is repeating so often, it will be really helpful.

A similar issue still exists. Faced this in Safari when Draft.js is updating the editor state. The error which I see: IndexSizeError: The index is not in the allowed range.

For me, playing around with Paragraph Directioncontext menus items after right-clicking on the Editor selection reproduced the error.

My Solution/hack: Add it to any JS file executing before the Editor file.

const nativeSelectionExtend = Selection.prototype.extend;

  Selection.prototype.extend = function (...args) {
    try {
      return nativeSelectionExtend.apply(this, args);
    } catch (error) {
      console.log('Selection error.', error);
    }
  };

It works properly for me. Maybe will be useful for somebody as well.
