When I read secrets using Vault Plugin from both Freestyle and Pipeline jobs, if secrets contains new lines e.g. '\n'. it gets substituted to space characters.

In actual contents in the secret:

multi lines contents

second lines

In vault JSON:

Unknown macro: {"key1"}

when it's been read from Vault plugin to a job,

"multi lines contents second lines"

 Please let me know if you need further detail.

Thanks in advanced.
