'bcrypt' has no attribute '__about__' in docker

[nerdalertdk]

When booting/starting ots in docker for the first time I get this error. When booting again it works fine.

I don't have an config.yml first time I boot. ots is creating the default for me

• Python 3.12.3
• OTS: 1.1.4
• docker base image: python:3.12 Debian bookworm based

Looks like bcrypt 4.1.1 might have a bug

https://github.com/langflow-ai/langflow/issues/1173

[nerdalertdk]

https://pypi.org/project/bcrypt/4.1.0/

[nerdalertdk]

fixed it by adding

RUN pip3 uninstall -y bcrypt && pip3 install bcrypt==4.0.1

in my Dockerfile

Thanks for reporting this, I noticed that message too. It seemed to be just a warning and everything still worked so I didn't do anything about it. I'll do some test after downgrading bcrypt to see if there are any side effects or if everything still works.

Still see this on login also

My code from https://fastapitutorial.com/blog/password-hashing-fastapi/:

from passlib.context import CryptContext

pwd_context = CryptContext(schemes=["bcrypt"], deprecated="auto")

class Hasher():
    @staticmethod
    def verify_password(plain_password, hashed_password):
        return pwd_context.verify(plain_password, hashed_password)

    @staticmethod
    def get_password_hash(password):
        return pwd_context.hash(password)

h = Hasher.get_password_hash("supersecret1234")
check = Hasher.verify_password("supersecret1234", h)

print(h)
print(check)
