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.
https://en.wikipedia.org/wiki/Base64#Base64_table

So best is to check if the string you are trying to decode contains something like this.
