I get "EPMAT-1:Command failed to execute" error on the importsnapshot step of groovy script

I get "EPMAT-1:Command failed to execute" error on the importsnapshot step of groovy script which allows to migrate the snapshot from source to target environment. I don't understand what's wrong, could you help me please?

EpmAutomate automate = getEpmAutomate()

//Log into the target environment

EpmAutomateStatus loginstatus = automate.execute('login','xxxx.xxx@adeo.com','targetPassword.epw','https://epm52-test-xxx.epm.em2.oraclecloud.com/')

if(loginstatus.getStatus() != 0) throwVetoException(loginstatus.getOutput())

println(loginstatus.getOutput())

//Recreate the target environment

EpmAutomateStatus recreatestatus = automate.execute('recreate' , '-f' )

if(recreatestatus.getStatus() != 0) throwVetoException(recreatestatus.getOutput())

println(recreatestatus.getOutput())

//Copy Artifact Snapshot from the source environment 

//to the target environment
