Floating license with docker

Hello I'm trying to launch the test with docker and I have some issue :

16:12:45,069 WARN  [SoapUIProGroovyScriptEngineFactory] Missing scripts folder [/scripts]

No valid ReadyAPI Test license exists.

Please enter the absolute path of the license file (.zip or .key):

Here my script : 

docker run -v "/Users/username/Documents/readyapi":/project \

-e SLM_LICENSE_SERVER="true" \

-e API_KEY="xxxxxxxxxxxxxxx" \

-e COMMAND_LINE="-r -a -j '-RJUnit-Style HTML Report' -FXML '-EDefault environment' '/project/readyapi.xml'" \

-it smartbear/ready-api-soapui-testrunner:latest

I use floating license so I don't have any (.zip or .key) file (trial period)
