Cannot publish plan because pad block is corrupted

[Jonathan Joseph]

I'm getting the following error when I attempt to publish my plan (using bamboo specs): 

2019-01-08 09:45:13,121 INFO [BambooServer] Publishing plan TO-CORSBO

Process finished with exit code 1

 
I'm running version 6.6.2

Any ideas on how I can fix this?

Figured out that Bamboo had issues encrypting the .sshPrivateKey() and .sshPublicKey() methods generated by Bamboo when exporting a plan's specs. 
Commenting them out fixed my issue and I was able to publish.
