Bug: Planner structure output crashes

[isaacmichaud]

If the planner if given a complex enough task to plan, the plan it generates may be so large that the LLM will not be able to generate a valid JSON string. URSA currently throws an unhelpful error. We should (1) provide a better error message that catches the LangChain StructuredOutputParser failure and (2) see if there is an automated way of rescoping the problem so that the planner can handle complex tasks with hierarchical planning.

Is this a general issue or in the one specific environment that you brought up on Teams? If just that env, we can probably close this. If its more general, lets deal with it.

I would like to check if there is an error message we should add to make the error more obvious. If there isn't a good way of doing that I will close the issue.

This was environment specific so I'm closing it for now. We can come back to it if it becomes an issue again in the future.
