Could not establish connection. Receiving end does not exist

why did this command send this error? Could not establish connection. Receiving end does not exist.
{
“Command”: “click”,
“Target”: “xpath=//*[@id=“contenedor_principal”]/form/fieldset[2]/table[5]/tbody/tr[2]/td/div/div”,
“Value”: “”
}
the command runs successfully multiple times and then this error occurs

This is a bad xpath do not use thiese types of xpath necause can change periodically

You must choice generic xpath to prevent dinamic element in page

@Juan_Daniel_Sanchez Do you have a test case?

Usually UI Vision reports this error if something goes wrong inside the website, e. g. a tab was closed or similar.

hi

the problem comes when pressing a button. I tried this ways but nothing happends

{
“Command”: “click”,
“Target”: “xpath=//[contains(text(),‘Siguiente’)]",
“Value”: “”
},
{
“Command”: “click”,
“Target”: "xpath=//
[@id=“botonFirma”]/span[2]”,
“Value”: “”
},

{
  "Command": "XClick",
  "Target": "siguiente.png",
  "Value": ""
},

this is the code in the page
("#botonFirma").button({ icons : { primary : "ui-icon-check" } }).click(function() { (’#box’).show();
if (validarEntradaJuridicaInteresado() != false && validarDireccionRepresentante()!=false &&
validarEntradaJuridica() != false && validarDireccionInteresado()!=false && validarEntrada() != false) {
if (!document.getElementById(‘alertaMail’).checked){
('#overlay').fadeIn('fast',function(){ (’#box’).animate({‘top’:‘160px’},500);
});
} else {
altaRegistro();
}
}
});

Siguiente

its like the click was done but nothing happends
