@Abisha - Can you post your ditamap file here?
It looks like a broken DITA file. We need to check your files for broken DITA syntax.
You have 3 errors/warnings highlighted -
1. An element type is required in the declaration of element type "desc"
2. Unable to parse invalid href attribute value "Section 4 Heat Treatment=GUID----=en=.xml"
3. [move-meta] java.io.FileNotFoundException- The system cannot find the file specified
1 & 2 seem to be associated with the ditamap file itself, while 3 might be due to the lack of compilation due to 1 & 2.
Thanks,
Rohan Garg
