warning: outdented heredoc line. The contents inside the heredoc should be indented at the same level as the closing """. The following is forbidden:

    def text do
      """
    contents
      """
    end

Instead make sure the contents are indented as much as the heredoc closing:

    def text do
      """
      contents
      """
    end

The current heredoc line is indented too little
