Ktra panics when using Mongo db backend
jbeaurivage opened this issue · comments
Ktra panics when trying to use the MongoDB driver with Ktra. This seems to stem from an incompatibility between tokio versions (ktra - tokio 1.1, mongodb - tokio 0.2). Here is a backtrace -

There is nothing we can do about incompatible async runtime. But in this specific case, I think it can be resolved by upgrading mongodb to 2.0.0 or above, which depends on tokio 1.0
Our issue here is that we weren't able to make cargo resolve tokio versions somehow. That would have prevented compilation and forced us to find out the issue. But for the time being a bump is probably a good idea. It'll come in 0.7.1, once we sort out the release situation (#52)

I figured as much. I tried upgrading to the latest mongodb in my fork with the intention to submit a PR, but I'm really too unfamiliar with how Mongo works so I didn't manage to make it compile unfortunately.
