180656: Field: <value> in the <value> table could not be changed from [Nullable] to [Non-Nullable] due to existing data.
Description
The table contains existing data, which prevented a field property from being updated to non-nullable.
Solution
Do one of the following:
Create a new version of the table, run the upgrade tool, and append the data from the original table to the updated table.
Take no action. The nullable properties of fields do not affect how data is used in the Indoors apps.
