Is there an existing issue for this?

• I have searched the existing issues

Appium Version

Appium Host Type

Command Line

Are you using Appium components not maintained by the Appium team?

No response

Is this issue reproducible using the latest components?

• I confirm the issue is still reproducible with the latest component versions

Current Behavior

An error occurs when executing the Back method.

Expected Behavior

My code is protected by try except. Even if EC.visibility_of_element_located(("accessibility id", "Back") cannot find the element, is it possible to not have an exception? How can I modify the code?

Now the process is completely stuck because of this step error.

self.driver.execute_script("mobile: swipe", {"direction": "right"})
Is this a problem with the execution?

My code is protected by try except. Even if EC.visibility_of_element_located(("accessibility id", "Back") cannot find the element, is it possible to not have an exception? How can I modify the code?

If you meant you won't raise an exception for find_element, find_elements will help. It will return an empty string if no elements are available. Asking such a question in https://discuss.appium.io/ will also helpful
