Expected Results

I should have a parameter separator in both envs.

Actual Results

getting an exception
My Jenkins pipeline is failing with the following

Anything else?

The RLC_MODE is not an actual error. when I remove the parameter separator it is working. this is the beginning of the Jenkinsfile:

separatorStyle = '''
border: none;
'''

sectionHeaderStyle = '''
color: navy;
font-family: Roboto, sans-serif !important;
font-size: 20px;
padding: 5px;
text-align: left;
border-bottom: 1px solid navy;
'''
properties([
parameters([
[
$class: 'ParameterSeparatorDefinition',
name: 'SEP_NODES',
sectionHeader: 'Working Nodes',
separatorStyle: separatorStyle ,
sectionHeaderStyle: sectionHeaderStyle
],

Are you interested in contributing a fix?
