I've been trying to set up the use of the Chrome DevTools using Selenium 4 and Python. I've been able to get it to run locally (without any of the async stuff), but when I try to use the webdriver.Remote implementation, it crashes.
Here is an example from the Selenium docs: https://www.selenium.dev/de/documentation/support_packages/chrome_devtools/
Below is how I tried to run it.
import asyncio
from selenium import webdriver
import selenium.webdriver.common.devtools.v96 as devtools
async def geo_location_test():
try:
chrome_options = webdriver.ChromeOptions()
driver = webdriver.Remote(
command_executor='http://D5365900:4444/wd/hub',
options=chrome_options
)
async with driver.bidi_connection() as session:
cdp_session = session.session
await cdp_session.execute(devtools.emulation.set_geolocation_override(latitude=41.8781,
longitude=-87.6298,
accuracy=100))
driver.get("https://my-location.org/")
finally:
driver.quit()
async def main():
await geo_location_test()
if __name__ == "__main__":
asyncio.run(main())
It runs up to the line async with driver.bidi_connection() as session: (session is established and Chrome browser opens). But the it crashes with the following trace.
Traceback (most recent call last):

As you can see, I'm using Python 3.10. I also upgraded the Selenium bindings to 4.1.0 and am running a Selenium 4.0.0 Hub/Node config to automate Chrome 96.
Any ideas, what is the problem here? Am I handling the asynchronous coroutines incorrectly?
Any help is much appreciated!
Update
After trying to run it with trio (as suggested in Henry Ashton-Martyn's comment), I get the following error.
Traceback (most recent call last):

It seems that selenium doesn't use python's builtin async framework but uses a package called trio as well. You should be able to fix this problem by changing this code from:
if __name__ == "__main__":
asyncio.run(main())
to:
if __name__ == "__main__":
import trio
trio.run(main)

JanusGraph 0.2.0 uses Apache TinkerPop 3.2.6. You should use the 3.2.6 version of the gremlinpython driver.
pip uninstall gremlinpython

In my application, an "Adapter does not support geometry" exception is being thrown when attempting to create a field of type, "geometry()". For my test application, I'm using an sqlite DB (production will use postgres):
db = DAL('sqlite://storage.sqlite', pool_size = 1, fake_migrate_all= False)
The DB table in question is declared within a class, inside of a module, and contains a several fields, some of which contain location data:
from gluon.dal import Field, geoPoint, geoLine, geoPolygon
class Info(Base_Model):
def __init__(...):
try:
db.define_table('t_info',
...
Field('f_geolocation', type='geometry()',
label = current.T('Geolocation')),
Field('f_city', type='string',
label = current.T('City')),
...
except Exception as e:
...
Edit:
As per Anthony's suggestion, I've modified the DAL constructor call to the following:
db = DAL('spatialite://storage.sqlite', pool_size = 1)
It produces the following error message:

If you want to use geometry fields with SQLite, you must use the spatialite adapter, which makes use of the SpatialLite extension for SQLite:
db = DAL('spatialite://storage.sqlite', pool_size = 1)
Note, you must have spatialite installed for this to work.
