Problem with starkex when creating order

[greenfield-br]

hi there. i had it and solved it. the problem is that when you sell, size should be positive, not negative,
the ORDER_BUY_SIDE, ORDER_SELL_SIDE makes up for the signal in size.
that is confusing at first, because when you get the account/openpositions/market data, selling side come as negative.
so, don rely on negative sizes for expressing selling, only for interpreting them.
best regards to all the community.

I have the same issue. Any thoughts on how to fix it?

I have the same problem but not always. I'm not sure what is causing it. Here's my error's traceback:

562, in submit_order
res = self.client.private.create_order(
File "/opt/homebrew/lib/python3.9/site-packages/dydx3/modules/private.py", line 571, in create_order
order_signature = order_to_sign.sign(self.stark_private_key)
File "/opt/homebrew/lib/python3.9/site-packages/dydx3/starkex/signable.py", line 32, in sign
r, s = sign(self.hash, int(private_key_hex, 16))

self._hash = self._calculate_hash()

assert 0 <= x < FIELD_PRIME
AssertionError

[UPDATE]: It works fine with buy/entry orders, but I get the error with sell/closing orders.
