Extensions like uBlock are preventing the script from loading

Good day,

We noticed that content-filtering extensions like uBlock are preventing the downloading of the analytics library.

We are using @analytics/amplitude and I was hoping to utilize customScriptSrc to proxy the library through our domain, but in your code, it is doing a checksum verification, so I might need to fork it to remove that check, but before I do that…

Have anyone found a workaround to this?

Updated the integrity check via @analytics/amplitude@0.1.2

let integrity
if (integritySha) {
   integrity = integritySha
} else if (!customScriptSrc) {
   // use default
   integrity = 'sha384-u0hlTAJ1tNefeBKwiBNwB4CkHZ1ck4ajx/pKmwWtc+IufKJiCQZ+WjJIi+7C6Ntm'
}

@DavidWells Have you had a chance to test your fix?

I just tried passing a public S3 URL and integritySha, but getting:

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'init').

Was quickly debugging locally, but the execution doesn’t even go into:

      // Initialize amplitude js
      (function(e, t) {

Based on this line:

const integrity = integritySha || 'sha384-u0hlTAJ1tNefeBKwiBNwB4CkHZ1ck4ajx/pKmwWtc+IufKJiCQZ+WjJIi+7C6Ntm'

integritySha always has to be provided, can we disable it? so if it’s not provided - we just don’t perform the integrity check.
