Recently while working in a visual studio 2015 workflow for SharePoint online (Download PDF for FREE), I received the below error while running the workflow for a particular list item. The workflow went to a suspended mode and the error comes as:
An unhandled exception occurred during the execution of the workflow instance. Exception details: System.UriFormatException: Invalid URL: The format of the URI could not be determined. The error looks like below:

My HttpSend Uri value looks like below:
The format of the URI could not be determined
Here the value which was coming in siteURL was like below:
https://onlysharepoint2013.sharepoint.com/sites/Bhawana (without “/” at the end)
So my HttpSend Uri was becoming like below:
https://onlysharepoint2013.sharepoint.com/sites/Bhawana_api/Site/RootWeb (missing “/” before _api)
So I changed my HttpSend Uri value to like below
Now it generates the URL correctly like below:
