Unable to open window in Ignition Designer v8.1.31

Ignition
1

Hello, I an unable to open one window in vision. It pops up this: "SerializationException: Error deserializing element ""
caused by IllegalArgumentException: Start point cannot equal endpoint"
Any help with this would be greatly appreciated.

Can you provide the full error / stack trace if there is one? There's usually a lot more error information available.

That said, this is usually the kind of thing you need to open a ticket with support for. They can take your gateway backup / project export / window export / etc... and try to "rescue" the window if necessary.

Not for sure if this is what you were looking for, but this is from the copy error button:

Yes, this has the additional info necessary.

Unfortunately you will have to contact support to get this window "rescued" or at least get a bug ticket open.
