Treating exceptions "Staleelementreferenceexception" from Selenium in Python

Question

I am developing a web automation to insert a list of numbers in a field on a website platform and click recurring within a "for" loop n times according to the dimension of the list. At first the code was right and making the query with the loop in this form:

for i in range(0, len(unique)):  
    driver.find_element_by_xpath('//*[@id="cph_j0_j1_UcEmpregador1_E_COD_CAMPO"]').clear() #Limpa campo
    ActionChains(driver).move_to_element(driver.find_element_by_xpath('//*[@id="cph_j0_j1_UcEmpregador1_E_COD_CAMPO"]')).click().perform() # Seleciona campo
    driver.find_element_by_xpath('//*[@id="cph_j0_j1_UcEmpregador1_E_COD_CAMPO"]').send_keys(unique[i]) # digita valor da lista
    driver.find_element_by_link_text('Consultar').click()
    ActionChains(driver).move_to_element(driver.find_element_by_link_text('Consultar')).click().perform()
    rand_time()

    if (driver.find_element_by_xpath('//*[@id="cph_j0_j1_GRADITIVO"]/tbody/tr/td').text) != 'Nenhum registro encontrado!':
        convenio_update.append(unique[i])

However, at the time of any of the iterations, the program is randomly interrupted by the message: "Staleelementereferenceexception: Stale element Reference: is not Attached to the page Document"

Researching the exception, the best way I could try to treat it, without success, was with the following code:

for i in range(0, len(unique)):
element_1 = driver.find_element_by_xpath('//*[@id="cph_j0_j1_UcEmpregador1_E_COD_CAMPO"]')
element_2 = driver.find_element_by_link_text('Consultar') 
try:
    element_1.clear() #Limpa campo
    ActionChains(driver).move_to_element(element_1).click().perform() # Seleciona campo
    element_1.send_keys(unique[i]) # digita valor da lista
    
    element_2.click()
    ActionChains(driver).move_to_element(element_2).click().perform()
    
    rand_time()
    
except NoSuchElementException:
    pass
    
except StaleElementReferenceException: #wait para os dois elementos
    element_1 = driver.find_element_by_xpath('//*[@id="cph_j0_j1_UcEmpregador1_E_COD_CAMPO"]')
    element_2 = driver.find_element_by_link_text('Consultar')
    
    element_1.clear() #Limpa campo
    ActionChains(driver).move_to_element(element_1).click().perform() # Seleciona campo
    element_1.send_keys(unique[i])
    
    element_2.click()
    ActionChains(driver).move_to_element(element_2).click().perform()
    
    rand_time()
   
finally:
    if (driver.find_element_by_xpath('//*[@id="cph_j0_j1_GRADITIVO"]/tbody/tr/td').text) != 'Nenhum registro encontrado!':
        convenio_update.append(unique[i])            

Someone would know to point out the error if the program is in the way or has some better alternative?

NOTE: I imported the following modules

    # IMPORTANDO BIBLIOTECAS
import pandas as pd
import random
from selenium import webdriver
from selenium.common.exceptions import StaleElementReferenceException, NoSuchElementException
#from   selenium.webdriver.common.by            import By
#from   selenium.webdriver.support.ui           import WebDriverWait
#from   selenium.webdriver.support              import expected_conditions as EC
