Laravel: array_merge(): Argument #2 is not an array error

Question

Exceptions started to appear in all views, and when I try to run composer update, it always ends up with

{\"error\":{\"type\":\"ErrorException\",\"m         


        

Answer 1

After a lot of searching and exploring each file in the 'app' folder, it appears that one file was corrupt

Delete app/storage/meta/services.json and re-run composer update and this should solve it.
