Uncaught Exception: FatalThrowableError

[aljawaid]

For Bolt 3.7

All contenttypes are working fine, except 'pages' and 'posts' (entries). I noticed the two have 'relations' which when I googled the error, seemed to be a fix applied in Bolt before 3.7.

FatalThrowableError on first contenttype with a relation when running app/nut database:export #7811 bolt/bolt#7811
I'm not sure if that is related.

Uncaught Exception: FatalThrowableError .

FatalThrowableError in LazyCollection.php line 24:
