function urlB64ToUint8Array(base64String) {
const padding = '='.repeat((4 - base64String.length % 4) % 4);
const base64 = (base64String + padding).replace(/-/g, '+').replace(/_/g, '/');
const rawData = window.atob(base64);
const outputArray = new Uint8Array(rawData.length);
for (let i = 0; i < rawData.length; ++i) {
outputArray[i] = rawData.charCodeAt(i);
}
return outputArray;
}
make sure you base64 is a valid Base64 string(ASCII string)

Hi! I'm getting the following error on my console that's preventing me from enabling the push notifications: main.js:37 Uncaught DOMException: Failed to execute 'atob' on 'Window': The string to be decoded is not correctly encoded. at urlB64ToUint8Array (http://127.0.0.1:8887/scripts/main.js:37:26) at subscribeUser (http://127.0.0.1:8887/scripts/main.js:116:32) at HTMLButtonElement. (http://127.0.0.1:8887/scripts/main.js:69:7)
urlB64ToUint8Array @ main.js:37
It's the line const rawData = window.atob(base64); that's in the function provided in main.js function urlB64ToUint8Array(base64String) { const padding = '='.repeat((4 - base64String.length % 4) % 4); const base64 = (base64String + padding) .replace(/-/g, '+') .replace(/_/g, '/');
const rawData = window.atob(base64); const outputArray = new Uint8Array(rawData.length);
for (let i = 0; i < rawData.length; ++i) { outputArray[i] = rawData.charCodeAt(i); } return outputArray; }
I am new to this and have no clue what is going on. Any help/clarification would be GREATLY appreciated. Thanks!
