Unwanted new line added to a long alert message causing an URL to be broken

Hi,
I am sending messages to two destinations AWS SNS Topic and Slack using the Kibana Alert feature.
A new line gets inserted into the URL thus the link is no more clickable. URL is 6750 characters long. I can see the new line insertion in the message, which is the root cause of the URL being broken in the slack message and email. There are other short URL which works fine, in the email and slack message it’s clickable.
Below is the message we send from Kibana

Monitor {{ctx.monitor.name}} just entered alert status. Please investigate the issue
