Python: planner json malformed

[silarsis]

https://github.com/microsoft/semantic-kernel/blob/f9bef6375cbb07dfe18948047a56ae9ab722ff62/python/semantic_kernel/planning/action_planner/action_planner.py#L116C24-L116C24

Frequently the json from the planner is erroring for being malformed, and I believe it's because of this line - it goes from, for example:

generated_plan_raw_str = '{"plan":{\n"rationale": "the list does not contain functions to generate apologies or any form of communication",\n"function": "",\n"parameters": {\n}}}\n#END-OF-PLAN'

To

generated_plan_str = '{"plan":{\n"rationale": "the list does not contain functions to generate apologies or any form of communication",\n"function": ",\n"parameters": {\n}}}'

Note the value of "function" in the json blob is now malformed.

Not sure why this line is here, perhaps it's dealing with a common issue elsewhere? But it seems to be the culprit...

Hi @silarsis, are you able to provide this exact code so we can easily repro it? Or is it a notebook/kernel example you're following? Thanks.

Ah, it's my own project - have a look at https://github.com/silarsis/assistant/blob/ab96ddefcb4dd48d6cbf48b0b80325eb66eb13e5/agent/models/guide.py#L157 but it's a bit of a dog's breakfast atm, being converted from guidance to sk. But that call should be relatively straightforward, and the prompt that got it there was "apologies for the debugger".

I think the problem is the planner isn't finding a function it can use so generating json with a blank string for the function name, and then the regexp is killing it.

Apologies for not responding for so long @silarsis. We've just release a Python beta package. Can you please try the latest code and let us know if you continue to experience an issue? I will close this for now. Do re-open or file a new issue. Thank you.
