sha256d() takes exactly 1 argument

[lewislin3]

When I'm mining with nightminer
I found there is an error mining bitcoin with sha256d().

[ERROR] ERROR: sha256d() takes exactly 1 argument (2 given)

my command:
python nightminer.py -o stratum+tcp://stratum.antpool.com:3333 -O USERNAME:PASSSWORD -a sha256d

Is my command wrong?

Change line 574 to
ProofOfWork = lambda s, m: (sha256d(m))
:)
