TypeError: 'NoneType' object is not subscriptable about fierce HOT 6 CLOSED

Could you provide the command you ran to get that exception?

from fierce.

Traceback (most recent call last):
File "./fierce.py", line 238, in

Again, if you could provide the command you ran to get this exception it would be helpful.

Also, this appears to be a separate issue, despite the exception being the same.

@mschwager same to me. the command info as following:

~/downloads/fierce # python3 fierce.py --domain baidu.com --subdomains accounts admin ads

Unfortunately I wasn't able to reproduce with the same command. However, after some digging I think I found the issue. I believe 8a51568 should fix it. Can you confirm @yangyangwithgnu or @hollow1?

@mschwager I am experiencing this error when attempting to enumerate sub-subdomains. For example

--domain "anything.google.com" 

Will throw the error.
