Answer 1

I believe your problem is due that you try to pass as a response argument a uiapp element. here a little variation of your script in html service.
the demo
the script:

// #### Part A
function doGet(e) {
  var html =""; // a text to be passed to script B
  html+="
"; // a place to display script B answer
  html+=""; // function to show the result of the urlfetch (response of script B)
  return HtmlService.createHtmlOutput(html);
}


function myClickHandler(text) {  
  var url = ScriptApp.getService().getUrl();
  var payload = { 
    name : "Gene",
    text : text,
    time : new Date()
  };

  var params = { 
    method : "post",
    payload : payload
  }
  Logger.log("text: "+text);

  var HTTPResponse;

  try{
    HTTPResponse = UrlFetchApp.fetch(url, params);
  }catch(e){
    Logger.log(e);
  }
  return HTTPResponse.getContentText();
}

// ###### Part B
function doPost(e){
  if(typeof e === 'undefined'){
    return "e was empty!!"; 
  }
  var htmlOut="
"; 
  for(var i in e.parameter){
    htmlOut+="
"+i+ " : " + e.parameter[i]+"
";
    if(i=="text"){
      htmlOut+="
 Text hash : "+Utilities.base64Encode(Utilities.computeDigest(Utilities.DigestAlgorithm.MD5, e.parameter[i]))+"
";
    }
  }
  htmlOut+="
";
  return ContentService.createTextOutput(htmlOut);
}

It is important to note that you won't have the ability to get the logger events of the script B (because it is triggered when you are not there - you are not the one who trigger script B. this is script A that's trigger script B and script A is not identified as "you" when it make a urlfetch). If you want to get the result of the script b logger you should return it to the script a. It's important to note: again, when script A do the UrlFetch to script B it is not identified as "you" so the script B must accept to be opened by anyone (in the publish option under "Who has access to the app:" you need to select anyone even anonymous).

NB: i put everything in the same script for commodity (you can split that in two differents script it's not a problem) and because B part need to be accessed to anonymous persons I can't retrieve automatically the email adress in the part A so I changed a little bit what was done here.
