anchor.diff:  Sometimes, you may upload a custom template. However, you may forget to upload the translation keys for it in the resource file. In such a case, the email will not be sent and you will see the following exception in the Kill Bill logs:
   
   [source,bash]
  -com.samskivert.mustache.MustacheException: No key, method or field with name 'text.merchantName' 
  +com.samskivert.mustache.MustacheException: No key, method or field with name 'text.merchantName'
   
   Ensure that you also update the translation properties as specified in the <<Uploading Resource files>> section above.

  As explained earlier, you can upload additional resource files for different locales or additional keys in existing resource files. In order to do this, please follow the steps given below:
  
  . Check if a resource file https://github.com/killbill/killbill-email-notifications-plugin/blob/6fc76403233fd5be290841ee6fc9d728028892f0/src/main/resources/org/killbill/billing/plugin/notification/translations/[already exists] for your locale. If so, download the file and if not, create a new file. You can use the https://github.com/killbill/killbill-email-notifications-plugin/blob/6fc76403233fd5be290841ee6fc9d728028892f0/src/main/resources/org/killbill/billing/plugin/notification/translations/Translation_en_US.properties[default translation template] as a reference to create a new file.
  
  . Add the required properties (key-value pairs) to your file.
  
  . Upload the new resource file using the following cURL command (Replace `<template-name>` with the name of the file created in the previous step and `<translation_key>` with the translation key. For example the translation key for a resource file for the `en_US` locale will be *TEMPLATE_TRANSLATION_en_US*):
