JSON.parse: unexpected non-whitespace character after JSON data on jwtExp

[VA1992]

On the version 2.3.8 I'm experiencing an issue with the jwtExp function.

unexpected non-whitespace character after JSON data at line 1 column 117 of the JSON data.

Rolling back to 2.3.6 fix the issue.

const middlePart = Base64.decode(token.split('.')[1]); <-- here a whitespace is included.

the issue here is in the Base64.decode function, for some reason is adding a whitespace when decoding the string.
A possible solution could be changing the decoder to use atob? it will save some time debugging the current implementation for the decoder.

file location: src/utils/base64.js
Method: decode

Patch:

var Base64 = {
     .....
     // replace current decode function 
    // public method for decoding
    decode: function (input) {
         return decodeURIComponent(atob(input));
    }
 }
