I was not able to add this new filed to my constructor which is not there in json and its throwing below error could someone please help me on this. I have tried two annotation @JsonIgnoreProperties and @JsonIgnore and @JsonIgnoreProperties(ignoreUnknown = true) and class level and constructor level
Below are my code and error details follow the same

You can try adding elemItems = driver.find_elements_by_css_selector(menuItemSelector)
for element in elements:
if element.text == "export":
elemItems[1].click()
annotation on field level. Or you can remove it from constructor and use setter method to assign value.
@JsonIgnore
