with base64, every three bytes (24 bits) of data is converted to four bytes
of printable data (6 bit). when you convert base64 back, you read 4 bytes at
a time and convert back to 3 bytes. you get this error when you don't have a
mulitple of 4. most likely the data is bad, you can append 1 to 3 '='s
to get the correct length (these convert to nulls). you should figure out
why your base64 string are actually invalid.

base64 string have to be even in length to be valid.
