how to solve this problem in line 163,164,167.

i have used an attached data set and trained the regression model using the regression learner toolbox. But when i export the model and type this two line in command window:

T=readtable('google_review_ratings');
yfit = trainedModel.predictFcn(T)

I get the following errors:

Function 'subsindex' is not defined for values of class 'cell'.

Error in mlearnapp.internal.model.DatasetSpecification>@(t)t(:,predictorNames) (line 163)
                extractPredictorsFromTableFcn = @(t) t(:,predictorNames);

Error in mlearnapp.internal.model.DatasetSpecification>@(x)extractPredictorsFromTableFcn(splitMatricesInTableFcn(x)) (line 164)
                predictorExtractionFcn = @(x) extractPredictorsFromTableFcn(splitMatricesInTableFcn(x));

Error in mlearnapp.internal.model.DatasetSpecification>@(x)exportableModel.predictFcn(predictorExtractionFcn(x)) (line 167)
            newExportableModel.predictFcn = @(x) exportableModel.predictFcn(predictorExtractionFcn(x));

the code is as follows ( its lengthy one)

kindly provide a solution. i will be very grateful to you.
