We need more information on the actual microflow, but you can research a bit more by using a breakpoint on the top of the microflow and then using the debugger to follow what happens in your app.
With the module you mention I expect that whatever endpoint you are trying to contact for the email information, is responding differently than you expect. With an empty body it might be a 200 response or another response with no body. Perhaps your endpoint is the wrong one? Or it's down?
Hi Saul,
The issue is caused by conflicting jars. Try to look if you have other mail related jars like from IMAP/POP3 incoming mail or email template module
Hi Saul,
Could you pls add screenshot of the microflow which is getting triggered on click of button?
