Event metadata link error

Hello,
I’m trying to send the link with AWS credentials via EventTracker to Intercom to include this URL and other attributes in the email to users. When I include the link as an event attribute( {{event.data-request.metadata.URL }} ) in the email, it malformed the URL which results in an error after opening the link in the email: "Error parsing the X-Amz-Credential parameter" probably because of Intercom encryption of these attributes. Is there any way to solve this issue or to pass the URL to email? Thanks
