If I open the Slack trace, there is this:

tryCatchOne(expr, names, parentenv, handlers[[1]])

doTryCatch(return(expr), name, parentenv, handler)

withCallingHandlers(expr = analysis(jaspResults = jaspResults, dataset = dataset, options = options), error = .addStackTrace)

analysis(jaspResults = jaspResults, dataset = dataset, options = options)

.frequentistComputeItemResults(jaspResults, dataset, options, model)

.seLambda3(dtUse[, -i])

.seLambda1(X, VC)

.varCM(X)
