[BUG] Error on import

[rnd42]

Describe the bug
Immediately upon importing beanie I get a TypeError.

To Reproduce
Run this code using UV run

# /// script
# dependencies = [
#   "beanie",
#   "motor<3.1",
#   "pymongo<4.2",
# ]
# requires-python = ">=3.10,<3.11"
# ///
import beanie

results:

$ uv run beanie_bug.py 
Installed 11 packages in 6ms
Traceback (most recent call last):

    InsertOne[Mapping[str, Any]],
TypeError: 'type' object is not subscriptable

I found that this is an incompatibility between Beanie 1.29 and pymongo < 4.2 given that the issue disappears with this patch:

$ git diff
diff --git a/beanie_bug.py b/beanie_bug.py
index 65be78b..d0e15e7 100644

$ uv run beanie_bug.py

Expected behavior
To be able to import and use beanie.

Additional context
I'm trying to thread a needle version wise to be able to use Beanie for an old Mongo 5.x server (motor<3.1, pymongo<4.2 which in turn requires Python >=3.8,<3.11) and FastMCP (requires Python >=3.10.)

Hi.
I can confirm that I get the same error as you do with your reproducer.

What I'm struggling to understand is what exactly are you trying to hunt down to achieve? Please rephrase your question better, without omitting some crucial information.
For me, any version of Beanie worked well with a MongoDB 5.x server. I've since migrated to MongoDB v7.
You can always pin down the dependencies for pymongo and motor accordingly, here's a pymongo-mongodb compability table:
https://www.mongodb.com/docs/languages/python/pymongo-driver/current/reference/compatibility/
According to motor documentation, even Motor version 3.0 supported MongoDB 5:
https://www.mongodb.com/docs/drivers/motor/#compatibility

What you mention here:

I found that this is an incompatibility between Beanie 1.29 and pymongo < 4.2 given that the issue disappears with this patch:

Beanie 1.29.0 is not compatible with PyMongo < 4.2 since that version of PyMongo did not have the Generic typing on the e.g. InsertOne class.
The only thing we (maintainers) can do is that we can also specify the supported PyMongo version ranges in beanie.

Yeah, fair enough. I think I had a misunderstanding reading the compatibility chart previously. Updating the dependencies is probably all that is warranted here. I appreciate your time in taking a look into it.
