Nvm. I see that this is for nested inputs!
(ArgumentError) could not find non-disabled input, select or textarea with name "account[users][]" within:
<input type="hidden" name="account[users][0][_persistent_id]" value="0"/>
<input type="hidden" name="account[users][0][id]" value="usr_00b9b8d493914e56a8d"/>
<input type="text" name="account[users][0][full_name]" id="account_users_0_full_name" value="Miss Cleta McKenzie" class="pc-text-input"/>
