@deekshith and in your controller you have:
public function getProjectDetail($type, $project)
{
}
?
You can try to use the full namespace of the controller as well: App\Http\Controllers\AdminProjectController@getProjectDetail.
I would personally name the route in the web.php or wherever you defined it and use the named route instead of action here:
Route::get(...)->name('project.details');
and use route('project.details', params) in the view.
