I have failed token transfer and I want to know why it was failed by reading contract source code. Is there any steps I can make to know on which line of the source contract code the execution was failed? I am not a contract developer, I want to know why concrete transaction was failed.
For example, how can I determine the line where contract was failed for this transaction: https://etherscan.io/tx/0x447b1c4ffd625601a55c0add8dde374d1d6fa3153b1e0e6babfd0dbe2cb90608
