Unable to decode base64 []: atob is not defined

Since https://github.com/upstash/upstash-redis/pull/198 I’m getting Unable to decode base64 []: atob is not defined warnings while running the library inside a Vercel API route.

I’m using automaticDeserialization, the feature might not be able compatible with it ?

Downgrading to version 1.13.1 does solve the issue, so it’s clearly that commit that caused the issue.

👍 I’ll leave this open until I merge the fix thanks for the report

if (typeof atob === 'undefined') {
  global.atob = function (b64: string) {
    return Buffer.from(b64, 'base64').toString('utf-8');
  };
}

I use this one for react native:

if (!global.atob) {
  global.atob = function atob(input) {
    var keyStr = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=';
    var output = '';
    var chr1, chr2, chr3;
    var enc1, enc2, enc3, enc4;
    var i = 0;
    input = input.replace(/[^A-Za-z0-9\+\/\=]/g, '');
    do {
      enc1 = keyStr.indexOf(input.charAt(i++));
      enc2 = keyStr.indexOf(input.charAt(i++));
      enc3 = keyStr.indexOf(input.charAt(i++));
      enc4 = keyStr.indexOf(input.charAt(i++));
      chr1 = (enc1 << 2) | (enc2 >> 4);
      chr2 = ((enc2 & 15) << 4) | (enc3 >> 2);
      chr3 = ((enc3 & 3) << 6) | enc4;
      output = output + String.fromCharCode(chr1);
      if (enc3 !== 64) {
        output = output + String.fromCharCode(chr2);
      }
      if (enc4 !== 64) {
        output = output + String.fromCharCode(chr3);
      }
    } while (i < input.length);
    return output;
  };
}
