Uncaught (in promise) TypeError: Cannot set properties of undefined (setting 'imscISD')

Hi Team,

I am using one library which internally uses imscjs library for CC handling. I am getting below error, do you know how to resolve or ignore this error ?

Uncaught (in promise) TypeError: Cannot set properties of undefined (setting 'imscISD') at 2206 (isd.js:809:42) at t (bootstrap:19:32) at 89953 (main.js:27:23) at t (bootstrap:19:32) at 69785 (hotkeys.esm.js:619:1) at t (bootstrap:19:32) at sharing:42:435 at t.m. (consumes:196:23) at t (bootstrap:19:32) at 46463 (8052.ff23f179.chunk.js:1:2899)

isd.js is creating issue, below is problematic code snippet, I am not even calling this file but somehow it get triggered, since imscISD is not defined globally, it is throwing error. (typeof exports === 'undefined' ? this.imscISD = {} : exports, typeof imscNames === 'undefined' ? require("./names") : imscNames, typeof imscStyles === 'undefined' ? require("./styles") : imscStyles, typeof imscUtils === 'undefined' ? require("./utils") : imscUtils );

can you please suggest if you have came across same issue earlier.

Regards. Abhishek

Can you provide more details on your runtime and development environment?

Hi @palemieux ,

Actually I am deploying on AWS using Jenkins and building using webpack.

imscJS is built using browserify, so there might be an incompatibility somewhere. Are you packaging imsc.js using webpack or building imsc.js using webpack?

@abhidev54 Does the proposed move to ES6 resolve your issue?
