There was 2 probability
1) brought the element, before actual content inside the element , ex. text
2) Had to request Headers
On 1st point
1) I applied "Explicit Waiting" by Python.
But it didn't still work.
2) So I thought of adding Headers
Additionally,
if the pb was related with "headers", then
I might try bs4 rather thatn Selenium, since it takes longer time
