Now Assist case summarization error

[Gianluca7]

Hi,
I'm facing an error while testing my prompt of case summarization with a clone of the OOTB Case summarization skill, this is the error message:

{ "error": { "sourceErrorMessage": "", "sourceErrorResourceId": "", "errorMessage": "Error in validating response: Response validator payload is undefined for definition b943b4f6872c0210fa6ecbfc0ebb35d5", "sourceErrorFeatureInvocationId": "" }, "status": "ERROR" }

I just added some fields as metadata at the top of the summary, like {{sn_customerservice_case.u_ordine_di_lavoro.number}} and I'm facing this error only for some cases, while for others it works. What is the issue here? How can I fix that?

Regards
