Hello, I'm a product manager from Appian who works on portals features. Have you tried checking the logs for your application to troubleshoot further? A 500 error means it's an error the product didn't anticipate, which is why there isn't additional useful details in the error message. We'd be interested to know what caused the 500 error if you could share, because it might represent a possible enhancement we could make for the future. Thank you!
Hey!
Can we use service call inside portal interfaces?
The Appian documentation says YES and also explains how to do it.
