AssertionError [ ] -- No transactions found <--- is this a bug ?

Hello, I have been experiencing the same problem over and over again. I tried to tome up with different try-excepts, unfortunately none of them worked. Is it possible that you can write a try except code to avoid this assertion error? Thank you.

I get what you mean.

I am afraid that this is a problem on BSCScan's side though, because they treat an empty list of transactions as an erroneous case, returning status code 0. From my side, if JSON response includes a status code of 0, I blindly handle it as an error and throw an exception. This is because a status code 0 may imply that either there are faulty parameter values or the address has no transactions.

For example:

• Request 1 originally returns status code 1
• Request 2 originally returns status code 0, thus it is handled as an error by this package
