I am running bayesopt and have encoutered the following error several times. It happens only when I use the runParallel option. Could anyone help me with that?
Dot indexing is not supported for variables of this type.
Error in BayesianOptimization/fitObjectiveFcnGP (line 2657)
KernelParameters = ObjectiveFcnGP.KernelInformation.KernelParameters;
Error in BayesianOptimization/fitGPModels (line 2600)
this.ObjectiveFcnGP = fitObjectiveFcnGP(this, BullAdjustment, BullAdjustmentN, useFitMethodNone);
Error in BayesianOptimization/chooseNextPoint (line 2295)
this = fitGPModels(this, true, BullAdjustmentN, false);
Error in BayesianOptimization/chooseNextPointParallel (line 2353)
BO2 = chooseNextPoint(BO2);
Error in BayesianOptimization/runParallel (line 2095)
this = chooseNextPointParallel(this);
Error in BayesianOptimization/run (line 1939)
this = runParallel(this);
Error in BayesianOptimization (line 457)
this = run(this);
Error in bayesopt (line 323)
Results = BayesianOptimization(Options);

A common cause of this kind of message is if a stage returns an empty array when the code expects it to return a struct or object.

I get the same error and the XAtMinObjective is an empty array. I have rectified the issue by picking XAtMinEstimatedObjective when that happens.
I don't know why XAtMinObjective is an empty array though. Is it because there are multiple X values where the minimum happens?
