Hello!

The same problem here when updating to fastapi==0.100.0 and pydantic==2.0.2.

lbenno · 2023-07-15T07:52:24Z

I get this error simply by importing fastapi_jwt_auth or any fastapi_jwt_auth Class. Even if the package/Class is not called.

fastapi==0.100.0
fastapi_jwt_auth==0.5.0
pydantic==2.0.2

Brandl · 2023-07-15T16:41:54Z

For me I could fix the issue by downgrading to:

fastapi==0.99.1
fastapi_jwt_auth==0.5.0
pydantic==1.10.11

Since this repo has not seen any movement in two years, this might be the only solution available until a fork appears.

subut0n · 2023-07-19T16:56:16Z

Hey,
I am also blocked right now by this problem. I can't downgrade the packages for some project reasons. I think I will also need an alternative or build my own solution. Hope to see an update on this lol. If anyone has a solution for this, ping me please

georg-mayer · 2023-07-29T08:56:08Z

I get the very same error.

thanks for the workaround, which does the job for me for the moment.

brouberol · 2023-07-29T09:00:15Z

@georg-mayer If that can help, this PR shows how I migrated a project of mine from fastapi-jwt-auth to fastapi-jwt to circumvent this issue. With pydantic 2.0.0 being out and fastapi-jwt-auth not having been updated for the past 3 years, I think this might be a good way forward.

madmanRE · 2023-08-03T20:58:25Z

thx for solution!

Same issue

chengdujin · 2023-10-20T14:31:41Z

Any good replacement for fastapi-jwt-auth?

thuyng-ing · 2023-11-15T13:56:54Z

Any good replacement for fastapi-jwt-auth?

No, the last time, I used https://github.com/GlitchCorp/fastapi-another-jwt-auth as an alternative but seems like the maintainer abandoned it.

brouberol · 2023-11-15T14:12:59Z

To re-iterate #98 (comment): I've had good success using https://github.com/k4black/fastapi-jwt as a replacement library. Some changes in the codebase were required, but not much.

avatar-lavventura · 2024-01-01T15:16:51Z

Is there any update regarding this to issue in order to make it work with pydantic==2..?
Is there any alternative or fork for fastapi-jwt-auth ?

You will need to change Sequence type to List type in config.py file in the LoadConfig class.

Using it from this fork resolved the issue for me. I just bumped the pydantic version to 2.7.0 without any application errors.
