Please correct the XML data and try again with simple settemplate

Question

So I have set a really simple set template for the checkout cart to be edited.

Module vendor/name : Designit/LiveUpdate

Designit/LiveUpdate/view/frontend/layout/checkout_cart_index/xml :

<referenceBlock name="checkout.cart.form">
 <action method="setTemplate">
 <argument name="template" xsi:type="string">Designit_LiveUpdate::cart/form.phtml</argument>
 </action>
</referenceBlock>

Everything seems to work fine but i have a bunch of errors in system.log now :

Any idea what I'm doing wrong? I've used this method before to change other things.

NOTE :

I'm not having any issue with the template itself. It works. Its only the error that i get which seems to have no consequences at all.

Do not link me duplicates if they do not specifically talk about this scenario where you have 1 xml , 1 template fille , template works fine and xml has only a setTemplate.

• Vino: Refer This link magento.stackexchange.com/questions/159819/…
• CompactCode: I already saw that solution but i'm not using that in any way.
• CompactCode: I just use a template fille and thats it
• Ben Crook: I think some (possibly all?) of those errors come from core, I've had those same/similar errors on every M2 site I've looked at and some have had very minimal changes applied
• CompactCode: People.. Please read. i'm not having issues adding a template. It works fine. Its just the errors that it gives what concerns me...

There are multiple issues on Github about this and the conclusion is that these errors are a "known issue", no-one really cares to fix them, and they're not actually Critical. Discussed for example here: https://github.com/magento/magento2/issues/5627
