As utity uses ES6 features like arrow functions it might b not available for IE.

Could you please try to convert typescript to es5?

Hi Anomepani,

yeah, I tried but no help. getting same errors

[anomepani]

I would suggest using ES5 Batchutils https://github.com/anomepani/sp-rest-util/blob/master/BatchUtils.js,
As I have used fetch API which is not available in IE10-11 browser so you can use polyfill.

Hope this will helpful to you
