    856 Links generating "Internal error: No Viewer defined or doesn't exist."

    • Article Type: General
    • Product: Aleph
    • Product Version: 18.01

    Description:
    the 856 link called by the MEDIA service is throwing this error:
    Internal error: No Viewer defined or doesn't exist.
    and the icon does not load.

    Configuration looks correct.

    Resolution:
    The following tables were missing:
    alephe/tab/tab_z403_directory.eng
    alephe/tab/tab_z403_extension.eng
    alephe/tab/tab_z403_info.eng

    Obtaining those tables solve the problem. These tables can be found in the ./alephe.orig/tab directory. Copy these to the alephe/tab directory, and restart web server.
