I'm not sure if this is the correct group to post this but this is gonna be my first post. I'm working on a change request and testing works fine until I encountered a
Publishing of mapping is aborted due to Failed to Publishing mapping. Reason is: Server responds: 500 Internal Server Error.

when I attempted to publish the same mapping after I applied the changes. I'm doing this in Eclipse with Keystore for MultiTenant (Mingle). I was able to republish the same map several times then all of a sudden I got that error.
I tried deactivating the agreement by going to ECA -> Server -> Agreement Status -> MyMap -> Deactivate. For some reason, it won't deactivate and there are no errors.
I tried Unpublishing and Removing the map via Eclipse but it won't let me because the agreement is still active.
I did some research and found that 500 Internal Server Error means The Gateway was unable to complete the request. As described by Design Center User Guide Version 14.1.7.2

I'd appreciate if someone can explain or suggest a resolution.
Thank you.
