when I click on the formula builder, f(x), button
I get an We're sorry, an error has occurred
Object reference not set to an instance of an object.
Unfortunately, as much as we try to avoid errors, these things tend to happen.
I am a site collection administrator. Happens on all sharepoint sites here.
Is this a new Nintex Forms installation or had it been working for a while before this started occurring? If you were to create a brand new form would it happen there if you were to try and create a calculated field with formula on the form?
The form had been working before.
I have tried creating a blank workflow and clicking on the (fx) button in an action (think it was approval task) The error still occurs.
Do you have access to the IIS server? If you do, open IIS and restart IIS. You can right-click on the top node and select restart. You will probably have to do this after hours.
Here is an imager of the kind of message I get. This message happened when I clicked on the addressbook icon just about visible in the image.
Unfortunately I don't have access to restart the servers but hopefully someone will be in tomorrow to restart them.
I can t help thinking something has gone wrong in the back end somewhere. Just don't know what or why
This site is branded however I am getting the same issue in unbranded sites.
you should be able to use that correlation error ID to search the logs for a more helpful indication of what is going wrong. Speak to your admins to have a look at that for you?
This really does seem to be environmental. The ULS logs should reveal more details about what's going on when this happens. I'd suggest reaching out to Nintex Support, because they will be able to connect with you and dig deeper into the issue. This is one of those things were items on the backend will need to be looked at (possibly AD, UPS, or even network related issues). Thanks!
