 <item name="fee" xsi:type="array">
 <item name="component" xsi:type="string">Vendor_Module/js/view/checkout/cart/totals/myfile</item>
 <item name="config" xsi:type="array">
 <item name="title" xsi:type="helper" translate="true" helper="Vendor\Module\Helper\Data::getCustomText"/>
 </item>
 </item>
 ...
 ... 
 </arguments>
</referenceBlock>

Answer 1

You are not allowed to use translate attributes for <item> nodes that have xsi:type anything else other than string.
Just remove translate="true" from this line

<item name="title" xsi:type="helper" translate="true" helper="Vendor\Module\Helper\Data::getCustomText"/>

• Rahul: Thanks for replay. It's working if I remove translate="true". But it's working translation in multilanguage?
• Marius: you should include the translation in your helper class. So this line of xml just returns the result of Vendor\Module\Helper\Data::getCustomText. use __('Text here') inside your getCustomText method and the text will be translated without the need of the translate tag,
