Common issues

OBGE Configuration

  • Verify whether the Automation Engine OBGE is in fact installed and configured correctly. For more details, check our Installation Guide.
  • Make sure that the BGMD service is started on the Automation Engine OBGE Server and verify that the JDF Hot Folder for the WebCenter FileStore is started. When in doubt, try (re)starting.

Progressive Compression

The Automation Engine OBGE cannot handle .jpg or .jpeg files with progressive compression. The WebCenter Task Details will show a message that indicates the file type is not supported: "The file is either damaged or not supported."

More detailed information can be found in the Automation Engine OBGE task log.

If you uploaded a progressive .jpg, resave it without the progressive compression and upload it again.

Fonts not Embedded

Any graphics file you upload needs to be self-containing. If fonts are not embedded, the Task Details will show: Substitution font <FONT NAME> can not be found and Font <FONT NAME> could not be parsed. For more information on this specific issue, see:

Not Graphics

You uploaded a .zip file as Graphics, but it is not actually a Digital Film. For more information on this specific issue, see:

Special Characters

You uploaded a .zip file as Graphics, but one or more of the files inside the ZIP package contain a special characters such as an ampersand (&). To resolve the issue, rename the file(s), create a new .zip file and upload this as a new version.

UNC FileStore Path

During installation, the location of the FileStore folder needs to be specified using an UNC path (for example: \\COMPUTERNAME\FileStore). Make sure it does not point directly to a local drive.

  1. I think that we can also add AI files not saved as PDF Compatible in the common issues.

    For automation engine users it is already well known, but not for WebCenter users.
