@jacob.small , I tried with IFailuresPreprocessor, but it didn’t resolved the warning as well the files are created twice in the output folder. Also I went through the Failure classes in RevitAPI.doc but couldn’t find this warning in any of the classes.
Hence went with “LostAcisObjectsOnImport” which is similar to the error
