I am trying to decode a URL and getting this error. Any ideas on what's wrong?

input byte array has wrong 4-byte ending unit

{% set encoded_url = request.query %}
<h5>encoded: {{ encoded_url }}</h5>

{% set decoded_url = encoded_url|b64decode %}
<h5>decoded: {{ decoded_url }}</h5>

@Hubmonks I don't see anything in the HubSpot HubL Documentation, however, you could try the following filter which works in certain Jinja environments (hubl was originally based on jinja):

{{ encoded_string|b64decode }}
{{ decoded_string|b64encode }}

It most likely won't work but it's worth a shot. Otherwise, you could print the HubL string into a script tag and use the js function on the client side.
