problem with survey-text plugin with jspsych 6

[mez7]

Hello, I am trying to use the survey-text plugin of jspsych 6, but keep on getting an error when I push the trial, although I am trying with exactly the same syntax as in the tutorials, do you have any idea why this is happening ? Thank you very much !!, below the error:

Can you please share more of the code that is generating the error? It will help to have a reproducible example.

I think the error is caused by the way to handle default values of missing parameters. The following code includes all parameters and works fine:

Custom number of rows and columns

var survey_trial = {
  type: 'survey-text',
  questions: [
    {prompt: "How old are you?", value: "", rows: 15, columns: 40},
    {prompt: "Where were you born?", value: "", rows: 15, columns: 40}
  ],
};

I just realized why I am having trouble replicating the issue. It's because #507 fixed this and I'm testing the development branch. I will merge this soon and push a new version. In the meantime, if you download the latest version of the survey-text plugin from the master GitHub branch it should solve this problem.
