How to pass AWS Session as environment dependency in TileFactory ?

[AbhishekD15]

I have a private s3 bucket. I would like to access the Object URL from the routes defined in Tilefactory.
I have a role that I am using to create an AWS session. I would like TilerFactory to include AWS session in the environment. What I am doing atm is creating a custom TileFactory and using the environment_dependency top inject the AWS session.

from rasterio.session import AWSSession

class CustomTilerFactory(TilerFactory):
    
    def environment_dependency(self):
        session = get_assumed_role_session()
        aws_session = AWSSession(session)
        return {'session': aws_session}

The get_assumed_role_session() returns a session using the role to access the private bucket.

Unfortunately still getting 403. Could someone please guide me ? Thanks

I don't think this will change the result but usually I would do it like:

def environment_dependency():
    session = get_assumed_role_session()
    aws_session = AWSSession(session)
    return {'session': aws_session}


endpoints = TilerFactory(environment_dependency=environment_dependency)

Nope, I am still getting rasterio.errors.RasterioIOError: HTTP response code: 403. I am just wondering once we create an instance of Tilerfactory , is there a property or a way to check the env dependencies. I just want to verify what I am injecting is what is used in the routes.
