Ajax response from Twitter to Flask server shows error

Question

I am using a flask server to get AJAX response from a twitter page. I am sending the response as follows:

var getRes = $.ajax({
      type: 'POST',
      url: "http://localhost:5000/myApp",
      data: vals,
      contentType: 'application/json;charset=UTF-8',
      success: function(res) { console.log(res) }
});

When the response is sent to the server it is showing me the following lines:

Refused to connect to 'http://localhost:5000/myApp' because it violates the following Content Security Policy directive: "connect-src

I checked other SO questions regarding the same topic e.g., link where they mentioned to add meta tags in the html. As i am working with Twitter, how can I do the same?
