Cannot import ReferenceError

Ignition 8.1.17

Hello all,

We have a view on a Perspective page that stop to work suddenly.

It seems, a transform script use the copy.py library, that use the weakref.py library, that failed to import ReferenceError from exception (from exceptions import ReferenceError)

ReferenceError

The same view works when I start the project on a redundant gateway...

Not sure what to do with that. Does anyone have an idea? Otherwise I will need to call the technical support.

Hello vrautomation,

If you could check your pylib folder by navigating to C:\Program Files\Inductive Automation\Ignition\user-lib\pylib

Can you confirm if you have copy.py and weakref.py in this folder? If they are in the pylib folder I would suggest opening a support ticket so we can take a look at your project to confirm the issue.
You can contact Inductive Automation Support by going to the link below.

Yes the files are there.

I'll call the support.
Thanks!
