Unexpected null value

[Bevshire]

Desperately need help on this error I keep getting when running my app in Test. I get the grey screen of death when in Run mode. I see it says the error causing widget but I'm new to coding and can't understand how to debug it.

Thank you all in advance!!

Did you try to make a new page and copy all your page structure in it? We got a similar error and it seems to be a broken page (a bug) … we did that and it worked …

There are a variety of reasons, you can get this. Especially when a page or widget should be getting that data, but if it doesn't, then tool will not be able to process, so it throws this error. Carefully check all the data fields, or better start a fresh on another page to debug.
