“获取文本”命令上的陈旧元素引用异常

Question

当我尝试从字段获取文本时，出现过时元素引用异常。这是代码：

Get Text 
[Arguments] ${locator}
Wait For Condition return document.readyState=="complete"
Wait Until Page Contains Element ${locator}
Wait Until Keyword Succeeds 5 5 Identify Element ${locator}
Wait Until Element Is Visible ${locator}
Sleep 2s
${text} SeleniumLibrary.Get Text ${locator}
[Return] ${text} 

我在 ${text} SeleniumLibrary.Get Text ${locator} 命令上收到以下错误：

StaleElementReferenceException: Message: stale element reference: stale element not found (Session info: chrome=120.0.6099.225)

等待命令全部成功，但获取文本仍然失败。

    Wait Until Element Is Visible    ${locator}
    Sleep    2s
    ${text}=    Set Variable    ${EMPTY}
    :FOR    ${INDEX}    IN RANGE    3
    \    Run Keyword And Ignore Error    # Retry up to 3 times
    \    ...    ${text}=    SeleniumLibrary.Get Text    ${locator}
    \    ...    Exit For Loop If    '${text}' != '${EMPTY}'    # Break the loop if text is retrieved
    \    ...    Sleep    2s    # Wait before retrying
    [Return]    ${text}
