p4 sync pipeline script not syncing files after p4 plugin update from 1.8.12 to 1.9.6

P4 sync is not syncing files when used in pipeline script after updating p4 plugin from 1.8.12 to 1.9.6

Below is the pipeline script - 

stages
{
stage('Perforce Sync')
{
steps
{
p4sync charset: 'none', credential: 'Perforce', format: 'JenkinsSAPAutomationWorkspace', populate: autoClean(delete: true, modtime: false, parallel: [enable: false, minbytes: '1024', minfiles: '1', threads: '4'], pin: '', quiet: true, replace: true, tidy: false), source: depotSource('//depot/AIM_platfom/sap_trasaction_validator/... ')

}
{color:#FF0000}}

The script is working fine after downgrading the version to 1.8.12.

Attaching the p4 log for your reference. Please let me know if you need more information.

Thanks,
