Always getting 'invaild input value false' error when assigning variables

[aster]

Can any expert answer:

It can be found when viewing the running results in LLM, but when assigning a variable, it always shows that the input is empty and cannot be found. And both the assigned variable and the session variable are of the same type.

For example: LLM-1.structured_output.risk_level(string), session variable risk_leve (string)
