Survey Plugin Text Validation

[d-bohn]

Hello,

I am attempting to use the jspsychSurvey plugin to get basic demographics. I would like to use the text type to get age and perform basic validation that the participant a) indicated a number and b) indicated a number between 18-120. The text type has a validation argument that used regex to match the inputted text. I have set up the plugin like so:

const demos = {
        type: jsPsychSurvey,
        pages: [
            [
                {
                    type: 'text',
                    prompt: "Please enter your age in a number format", 
                    placeholder: '(e.g., 25)',
                    name: 'age', 
                    required: true,
                    validation: '^(?:1[01][0-9]|120|1[8-9]|[2-9][0-9])$'
                  }, 
            ]
};

While the plugin works as expected, I get the following warning in the console:

Warning in survey plugin: the following question parameters have been specified but are not allowed for the question type "text" and will be ignored: validation

And it indeed doesn't do any validation on the inputted data. Am I missing something? Any help would be greatly appreciated! Thanks!
