Native Build Failure

SOLVED! See comments for answer Hello Makers, I developed a native app in 9.12.1 and now I am trying to build it using the native builder by following the mendix documentation for the same but I am getting the following message after I start the build   I am new to building native apps and hence I have no idea here what is wrong and where to look to debug this issue.  Thanks. PS: This is an existing app of ours and we needed just wanted to add a native profile hence we migrated our application from mendix 8 to mendix 9.
