Hello Karthik Byggar san, Honoka san.
Thank you for your advice.
I tried to use Element Exists, but unfortunately Element Exists did not perform in sequence I build.
ErrorDialog which Element Exists is selected is shown as Figure 1 ‘要素の有無を検出’ and Figure 2.
But Element Exists is unusable, because Output(Boolean) of Element Exists is always ‘True’.
I think it is correct that errorDialog is object to be selected by Element Exists (see Figure 3).
I tried to change object to be selected (for example a text of ‘ご確認ください’ or ‘存在しない銘柄です’),
or to change location of Element Exists in sequence (for example location after saving image activity)
so that Element Exists would be able to find errorDialog.
But result of output(Boolean) is ‘True’ as usual.
Then according to Honoka san’s advice,
I tried to use click activity in sequence (see Figure 4 ‘クリック’ and Figure 5).
Click activity forced to click button ‘閉じる’ which means to close errorDialog
whether errorDialog is displayed or not.
I regret I could not use Element Exists, but I saved all images normally without errorDialog
when ticker was not existed.
