hands down one of the best runnables video out there. not to mention, the only runnable video. but still the best

very good video, nicely explained and clears up some uncertainties i had. Rn I want to create a Custom RunnableConfigurableFields, where I pass a JSON Schema for validation as a configurable. Something a bit cumbersome, which I also like is the usage of RunnableParallel to get data from the invocation of a chain which wont be passed through by for example an LLM call.

I like your Ideas with RunnableRetry and RunnableFallback, it makes everything more robust if you use Langchain in an api

I implemented a custom runnable, but it seems that langsmith doesnt show it inside the chain as a step like it does runnable lambdas and the langchain premade runnables. I wonder if you have had this problem as well
