This error would occur when crawler can't find form element requested; Quite tricky when you are using, for instance, form builder as when run, it will create different input name:

$form = $this-> createFormBuilder($store)
           ->add('storeNumber','text')
           ->add('storeName','text')
           ->add('save', 'submit')
           ->getForm(); 

will output field name like:

form_storeNumber

which should be used in test class:

$form=$crawler->selectButton('save')->form();
$form['form_storeNumber']='10';
