Trying to Access the lastBuildTime via the elasticubeMetadata in Linux

Trying to go into the Metadata being bulled in from the Dashboard in order to display whenever the last time the elasticube was updated last. Accessed this when using the windows version buy going into the Meta data can calling on elasticubeMetadata.lastBuiltUtc

after pulling in the datasource from the URL. Since switching over to using Linux now getting and error that

is stating it is undefined. Does anyone know if there was an update or change with the Linux version. I checked the Documentation and it Mentions trying to call it as lastBuildTime or Last Published but neither of these work.
