null error on filters for fields that don't exist (date time fields specifically)

[aaronmt93]

Can we access your project?

• [X] I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

Using a filter to get a number of items from a list of documents. This is a new field in my app so not all documents have this field in firebase. However, instead of the filter conditions defaulting to false when I set the default values, I get a null and the page has a giant red error screen breaking the UI.

Expected Behavior

If the fields dont exist, the filters should return false without resulting in a breaking change

Steps to Reproduce

1. add a text widget
2. query a list of documents that have a date time field somewhere
3. set the text to be equal to the number of items returned in a filtered set of documents
4. set the filter to check if the date time field in the list of documents is greater than the date time field in the users document (this is my use case, though even if I compare it to a static date time like the global property current time I still get the error)
5. for testing, make sure both of those date time fields don't exist
6. even with default variable to false, still get the null error

Additional Information

if ever a field is null in the database and a page references that field, results in a complete break in the UI of the app
