The error “Illegal base64 character 3a” indicates that the base64 string contains an illegal character.
Character 3a in the ascii table is a colon ‘:’, which is not part of the allowed characters.

So best is to check if the string you are trying to decode contains something like this.
data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAEEAAAAUCAYAAADStFABAAAJHElEQVRYCXVXWXObVxl
which character set is used to encode? And which characterset are you using to decode?
