Command 'Validate Jenkinsfile' resulted in an error (Cannot convert undefined or null to object)

Tried to run F1->Validate Jenkinsfile which resulted in "Command 'Validate Jenkinsfile' resulted in an error (Cannot convert undefined or null to object)". I configured settings but got no clue what's happening.

I'm getting the same error when I'm trying to use token authentication. The workaround for me was to put the token as the password. see https://github.com/janjoerke/vscode-jenkins-pipeline-linter-connector/issues/19#issuecomment-596307978

Would be fixed by #31
