How to debug RecursionError?

Open chbndrhnns opened this issue 3 years ago • 2 comments

I have a nested structure of containers and I wanted to perform some refactoring by adding the new container structure first and then gradually removing the current structure.

However, DI decides to throw a RecursionError and I'd like to debug that. Can anyone help how to do it? Here is the stacktrace so far. I was not yet able to narrow the example down to a minimal working example, unfortunately.

Have same issue. Any updates or solutions?

I have the same issue, temporarily fixed this by increasing the recursion limit for container initialisation. Which is not a perfect solution, but it works.

sys.setrecursionlimit(2000)
container = Container()
sys.setrecursionlimit(1000)
