I've been trying to figure out the following error when running a react project I'm working on.

"Cannot read properties of undefined (reading 'split')"

The error appears when adding a async fetch to grab some data from an API.

Recently just adding the following code to allow cross origin data fetching causes the issue with no fetch. Not fetching data or anything. It's rather strange.

const agent = new Agent({
    connect: {
      rejectUnauthorized: false
    }
  });
  
setGlobalDispatcher(agent);

I'll continue to try and lock it down and append any information here as I can see it's a bit vague.
