Why is my library import failing in DSM?

When importing a Craft Library into DSM, users may receive the following error message:
This error message can occur when DSM cannot read the file, if the file is in a format DSM does not support, or if the file is corrupt.
In some cases, the library may be able to be manually repaired while in other cases, you may need to reconstruct the library by re-importing colors, text styles, and components from Sketch directly into DSM rather than by using the Craft Library import feature.
For additional assistance with this error message, please contact Support.
