Answer 1

This is an Permission issue. You can Manage it by this way:

Keep the whole project permission as 644 and

find /desired_location -type d -print0 | xargs -0 chmod 0755
find /desired_location -type f -print0 | xargs -0 chmod 0644

Also Set User to your

chown -R Username:Username .

Now, Give Permission to this Folder as 777.

chmod -R 777 var/ pub/ generated/
