Error thrown in chrome parsing amp-worker.js

[dickie81]

Description

We have just noticed an error while parsing amp-worker.js introduced in this commit 54c0400 specifically around line 101.

    if (self.trustedTypes && self.trustedTypes.createPolicy) {
      const policy = self.trustedTypes.createPolicy(
        'amp-worker#fetchUrl',
        policy
      );
    }

As you can see just reading the code policy will be undefined.

Reproduction Steps

I can't list the site where this is occurring on as it is commercially sensitive. But if you paste the following code in the browser console it will demonstrate the general idea.

const x = 0;

if (true) {
  const x = alert(x);
}
