Unexpected Panic error in subfinder #1160
Description
Hell when I was testing performance subfinder each resources I faced panic error and the full error was :
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0xd57b8a]
goroutine 66 [running]:

and also Im not well in golang but when I tested the performance with my tool with subfinder and specially with resources I faced this error and after researching about this error I think it occurs when it try to read or write to the unallocated memory address and to analyze and handle this error I think the recover() built-in Go function will be helpfull and Im also attaching a screenshot about the error :
Kind regards,
