Part of the code on the right side

   switch (a.pathname){
    case "/CMD":
      pobj=JSON.parse(pdata);
      console.log(pobj);
      if(pobj.cmd !==null){
       eval(pobj.cmd);
       pdata=JSON.stringify(pobj);
       res.writeHead(200);
       res.end(pdata);
      }else{
       res.writeHead(201);
       res.end();
      }//end if pobj.cmd
    break;    //this is the break being flaged on line 94
    case "/LOGdata":
     console.log("LOGdata= ",pdata);
     res.writeHead(200);            // this is the line reported 97
     res.end(pdata);
    break;
    default:
     res.writeHead(404);
     res.end();
    break;
  }//end switch
 pdata="";
}//end doPost1

Changing the code removes the error.

function doPost1(req,res){
var length;
var a = url.parse(req.url, true);
console.log("URL ",a);
console.log("XXX ",a.pathname);
  length=req.headers["Content-Length"];
  console.log("Length ",length);
  console.log("pdata= ",pdata);
  console.log("pdata length= ",pdata.length);
  if(pdata.length!=length){
   res.writeHead(404);
   res.end();
   pdata="";
   return;
  }//end if length
   switch (a.pathname){
    case "/CMD":
     doCMD(req,res);
    break;
    case "/LOGdata":
     console.log("LOGdata= ",pdata);
     res.writeHead(200);
     res.end(pdata);
    break;
    default:
     res.writeHead(404);
     res.end();
    break;
  }//end switch
 pdata="";
}//end doPost1

function doCMD(req,res){
 pobj=JSON.parse(pdata);
 console.log(pobj);
 if(pobj.cmd !==null){
  eval(pobj.cmd);
  pdata=JSON.stringify(pobj);
  res.writeHead(200);
  res.end(pdata);
 }else{
  res.writeHead(201);
  res.end();
 }  //end if pobj.cmd
}//end doCMD
