decode not working with some data

[crazyjat]

The following encoded string will fail with the error "The string to be decoded is not the correct length for a base64 encoded string."

However, the above encoded string is a valid base64 encoded string. I have verified that it correctly decodes with the following online base64 decoders:

https://www.base64decode.org/
http://base64decode.net/

Although the length of this string is indeed not a multiple of 4, every other decoder I have used will add padding to the end of the string (IE. adding "==" or "=") to make it a valid length. Since this library simply fails, that is not very helpful.

@stranger82 @crazyjat is totally right. This library fails to match the length of the strings to multiple of 4.

{"fieldNames":[],"orderBy":{"name":null,"direction":null},"predicates":[{"attribute":"attributes.firstName","comparison":"starts_with","value":"a"}]}

However, https://www.base64decode.org/ converts it to
