TypeError: Cannot read property 'trim' of null

What's going wrong?

On version 3.4.0 when i type the command "pm2 show 0" the terminal show the "Describing process with id 0" square followed by the title "Revision control metadata" and the error:

/home/administrator/.nvm/versions/node/v10.15.1/lib/node_modules/pm2/lib/API/CliUx.js:161
{ 'comment' : pm2_env.versioning.comment.trim() },
^

How could we reproduce this issue?

my proyect are over an svn source control on a Centos 7 Linux, a node v10.15.1 and a npm v6.4.1
