Error when training a COX PLP model

Hey OHDSI forums,

We are trying to train a COX PLP model to predict the risk of recurrence within 3 years of colorectal cancer surgery. We have designed the cohorts in ATLAS, but need to design the remaining parts in R, as, for now, the COX model is not a part of the ATLAS prediction module.
However, when running the model in R we get an error, that we hoped you could help us with.

We have taken screenshots(export of actual scripts and log was not possible at the time of this post) of our model definition, the error log and R session info.
Please let us know if you need more information.
