Hi,
Rocket Chat API expects a boolean value for titleLinkDownload in attachements object.
cf : https://rocket.chat/docs/developer-guides/rest-api/chat/postmessage/#attachments-detail
When this is true, a download icon appears and clicking this saves the link to file.
This breaks the usage of attachements in the workflow pipeline syntax because it needs a string for titleLinkDownload. (MessageAttachment.java#L46)
e.g. :
rocketSend(
    attachments: [[
        title: 'My repository',
        color: 'red',
        text: 'unit test failed :sob:',
        thumbUrl: '',
        messageLink: '',
        collapsed: false,
        authorName: 'Zevran',
        authorIcon: '',
        authorLink: '',
        titleLink: 'https://github.com',
        titleLinkDownload: '',
        imageUrl: '',
        audioUrl: '',
        videoUrl: ''
    ]],
    channel: 'devops',
    message: '',
    avatar: 'https://github.com/fluidicon.png',
    failOnError: true,
    rawMessage: true
)
