Statamic v3.0.15
PHP v7.3
Hi Trying to add a nav menu which is linked to the pages collection. When trying to add a link to an entry this error is thrown - local.ERROR: Call to a member function field() on null {"userId":"b57f26d8- c943-4ad5-b74f-75be1563604a","exception":"[object] (Error(code: 0): Call to a member function field() on null at Users/steve/Code/publicwebsite_v3/vendor/statamic/cms/src/Data/DataCollection. php:223)
I have imported my Statamic v2 site using the migration tool so this might be causing the issue, any help appreciated.
