I have a sha256hash with this value XCehCf3Awy
it has Upper case ,Lower Case and Numbers
is the best method for this hash -a 3 ( BF)?
and im trying to use it like this :
hashcat -m 1400 -a 3 test.hash ?a?a?a?a?a?a?a?a?a?a
But Im getting this error :
Integer overflow detected in keyspace of mask: ?a?a?a?a?a?a?a?a?a?a
what is the correct usage for option -a 3 ?

Your use case is correct, it's just that you are giving it a very large keyspace. I think ?a is about 95 characters or so, meaning you're feeding it a keyspace of 95^10, which is quite large.
If there's no need for special chars, don't use ?a.
Instead use -1 ?l?u?d ?1?1?1?1?1?1?1?1?1?1
It will decrease the keyspace to 62^10. Still a lot, but maybe more manageable.

After I fixed it according to your instructions, it worked properly. Thank you.
