thread 'main' panicked at 'there is no timer running, must be called from the context of a Tokio 0.2.x runtime'

[Lucyfurnice]

When I include code in my main that syncs a model, or within a function that main calls, I get a huge stacktrace. thread 'main' panicked at 'there is no timer running, must be called from the context of a Tokio 0.2.x runtime'... I see there is an old issue on mongodb-rust-driver but i could not try because of version changes.

main

async fn main() -> Result<(), Box> { ... let db_client:Client = create_db_client().await.unwrap(); let db:Database = db_client.database("name"); Topic::sync(db).await; ... }

I did find that mongo-rust-driver is using tokio version = "1.17.0" I guess that would be the problem

I think my feature flags could be conflicting let me try to compile the tutorial.

cargo new mongotest cd mongotest cargo add tokio --features full cargo add wither --features tokio-runtime cargo add futures cargo add serde

Switching tokio to version "0.2.25" works. Wonder what is using that version...

[Lucyfurnice]

fixed with cargo add --git [this repo]
