The method user does only exist in Illuminate\Contracts\Auth\Guard, but not in Illuminate\Contracts\Auth\Factory.
It seems like the method you are trying to call exists only in some of the
possible types.
Let’s take a look at an example:
classA{publicfunctionfoo(){}}classBextendsA{publicfunctionbar(){}}/** * @param A|B $x */functionsomeFunction($x){$x->foo();// This call is fine as the method exists in A and B.$x->bar();// This method only exists in B and might cause an error.}
The variable $isOwner does not seem to be defined for all execution paths leading up to this point.
If you define a variable conditionally, it can happen that it is not defined
for all execution paths.
Let’s take a look at an example:
functionmyFunction($a){switch($a){case'foo':$x=1;break;case'bar':$x=2;break;}// $x is potentially undefined here.echo$x;}
In the above example, the variable $x is defined if you pass “foo” or “bar”
as argument for $a. However, since the switch statement has no default
case statement, if you pass any other value, the variable $x would be undefined.

Check for existence of the variable explicitly:
functionmyFunction($a){switch($a){case'foo':$x=1;break;case'bar':$x=2;break;}if(isset($x)){// Make sure it's always set.echo$x;}}
Define a default value for the variable:
functionmyFunction($a){$x='';// Set a default which gets overridden for certain paths.switch($a){case'foo':$x=1;break;case'bar':$x=2;break;}echo$x;}
Add a value for the missing path:
functionmyFunction($a){switch($a){case'foo':$x=1;break;case'bar':$x=2;break;// We add support for the missing case.default:$x='';break;}echo$x;}

Add an additional type-check:
Only allow a single type to be passed if the variable comes from a parameter:
