Error in strsplit(a, "[.-]") : non-character argument

Hello after trying to sumbit my R scribt to google cloud platform I always get the following error:
Error in strsplit(a, "[.-]") : non-character argument
I also tried running my script from a google cloud jupyter notbook out of fear that maybe I did not install something the right way. However I got again the same error. Does anybody of you guys now what Im doing wrong ?

Hi, I got the same error!
I managed to resolve it by creating a "cloudml.yml" file with the following arguments:
trainingInput:
runtimeVersion: "2.2"
pythonVersion: "3.7"
