Liferay.Language.get method is no longer working with string variables as of DXP 7.3

Issue

• Pieces of code which contain calls to Liferay.Language.get using string variables and not literal strings as their argument return the argument passed instead of the corresponding translation.

Environment

• DXP 7.3+

Resolution

• In previous versions, this works since there is a fallback to retrieve the translations located in the core through a blocking HTTP request in case that the first attempt to find the requested translation was not available within the module at render time.
• This fallback mechanism was removed as of DXP 7.3 because it uses a blocking HTTP request and that only covered one of the possible scenarios.
• There is no direct replacement. As a workaround, literal strings should be passed instead of variable strings, since the former ones can be preprocessed by LanguageFilter when this filter is enabled. As an example of adapted code:

  // Previous code
  
  let myStatus = 'draft-status';
  
  if (myCondition) {
    myStatus = 'published-status';
  }
  let myStatusLocalized = Liferay.Language.get(myStatus);

  // Adapted code
  
  let myStatusLocalized = Liferay.Language.get('draft-status');
  
  if (myCondition) {
    myStatusLocalized = Liferay.Language.get('published-status');
  }
